Description

The present invention relates to a handheld terminal , a control method for a handheld terminal , and a program.

On European high-speed trains, ticket inspections are carried out on board. If a passenger wants to board, the conductor will issue a ticket on board using a ticket issuing terminal. Passengers can pay for their tickets using a payment terminal with cash or credit card.

In recent years, business functions, ticket issuing functions, and payment functions have been integrated into terminals equipped with full touch screen displays, thermal printers, IC (Integrated Circuit) card readers, magnetic card readers, and contactless card readers. These terminals can be said to be integrated into a single business terminal in addition to being a ticket issuing terminal and payment terminal.

Conventionally, for mobile information terminals used for business purposes, a technology has been known that allows the use of certain functions only when a specified IC card is read in order to prevent unauthorized use by third parties (Patent Document 1).

JP 2008-211582 A

A terminal that integrates business functions, ticket issuing functions, and payment functions has the advantage that the conductor only needs to carry one terminal, and there is no need to manage batteries for each terminal. Another advantage of this terminal is that there is no need to connect via Bluetooth (registered trademark) or the like when starting work. However, this terminal has the following problems when issuing tickets and performing payment operations.

If the conductor hands this terminal to a passenger, there is a risk that the terminal may be subjected to unexpected operations. Also, if a passenger hands over their credit card to the conductor, there is a risk that the credit card may be misused. Conventionally, due to the demands of both the conductor and the passengers, the service terminal and the payment terminal were often separate.

The objective of this invention is to allow other users to use the information terminal while maintaining security.

In order to solve the above problems, the information processing device of the present invention comprises:
a determination means for determining whether or not a first authentication key is attached to the attachment portion;
a restricting means for restricting the start of a specific process when the determining means determines that the first authentication key is not attached to the attachment portion;
A display means;
Equipped with
The limiting means is
when the determination means determines that the first authentication key is attached to the attachment portion after the specific process is started with the first authentication key attached to the attachment portion, a guidance to remove the first authentication key is displayed on the display means, and when the determination means subsequently determines that the first authentication key has been removed from the attachment portion, acceptance of operations other than an input operation related to the specific process is restricted.
It is characterized by:

The present invention allows other users to use an information terminal while maintaining security.

The following describes in detail an embodiment of the present invention with reference to the accompanying drawings. Note that the present invention is not limited to the illustrated examples.

<Handheld terminal configuration>
Fig. 1 is a block diagram showing the hardware configuration of a handy terminal 100 according to this embodiment. Fig. 2 is an explanatory diagram showing the appearance of the handy terminal 100 and a schematic network configuration using this handy terminal 100. Below, the functions and operations of each part of this handy terminal 100 will be explained with appropriate reference to Figs. 1 and 2.

The handheld terminal 100 according to this embodiment is configured to include a SoC (System On Chip) 1, a memory unit 2, a barcode scanner 3, a barcode scanner controller IC (Integrated Circuit) 4, a thermal printer 5, and a thermal printer control IC 6. The handheld terminal 100 is further configured to include a contact IC card reader 7, a contact IC card controller IC 8, a button 9, a key controller IC 10, a liquid crystal touch panel 11, an LCD (Liquid Crystal Display)/TP (Touch Panel) controller IC 12, a communication unit 13, a communication-related circuit 14, a battery 15, and a PMIC (Power Management Integrated Circuit) 16. The handheld terminal 100 is also configured to include an NFC (Near Field Communication) communication unit 17, an NFC communication controller IC 18, a magnetic card reading unit 19, and a magnetic card controller IC 20, but these are not necessarily required.

The SoC1 is a semiconductor device that integrates various functions, such as a processor core, memory, and analog circuits, on a single integrated circuit chip. This SoC1 functions as a central processing unit that provides overall control of the handheld terminal 100.

The contact IC card controller IC8 is a discrimination means, and determines whether or not the business card 50 (first authentication key) is attached to the contact IC card reader 7 (attachment section). The SoC1 is a restriction means, and when the contact IC card controller IC8 determines that the business card 50 is not attached to the contact IC card reader 7, it restricts operations related to each business. When the contact IC card controller IC8 determines that the business card 50 has been removed after the payment process has been started with the business card 50 attached to the contact IC card reader 7, the SoC1 restricts the acceptance of operations other than input operations related to the payment process.

In this way, the SoC1 of this embodiment executes an application including a payment-related process as a predetermined process. The first authentication key corresponds to a key that controls the execution of a business-related application using the handheld terminal 100, i.e., the business card 50. The payment process using the ticket issuing application is one example, and is not limited to this.

The storage unit 2 is composed of a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM stores specific programs, and the RAM stores rewritable data. The SoC1 realizes each application by reading and executing specific programs for executing each application from the ROM of the storage unit 2. The applications are a timetable application, a ticketing application, a translation application, a route guide application, etc.

The barcode scanner 3 irradiates the barcode with laser light or an LED (Light Emitting Diode) and recognizes the barcode by reading it using a CCD (Charge Coupled Device). This allows the barcode to be decoded into letters, numbers, symbols, etc.

The barcode scanner controller IC4 is a controller IC that controls the barcode scanner 3.

The thermal printer 5 is a printer that prints on paper media using heat. There are two transfer methods for transferring data onto paper media: thermal printers that print on dedicated thermal paper, and thermal transfer printers that use ink ribbons. Either transfer method can be applied. Therefore, the thermal printer 5 can issue a receipt as a result of the payment process. As shown in FIG. 2, the thermal printer 5 is provided on top of the handheld terminal 100.

The thermal printer controller IC 6 is a controller IC that controls the thermal printer 5.

The contact IC card reader 7 is a mounting section for mounting the business card 50 or the passenger's credit card 51, and is provided at the bottom end of the handheld terminal 100 as shown in FIG. 2. The business card 50 and the passenger's credit card 51 are contact IC cards, and have a CPU (Central Processing Unit), ROM, RAM, and contacts (terminals) 52 (not shown), and the contacts 52 (see FIG. 4D) are exposed on the surface.

The contact IC card controller IC8 is a controller IC that reads information stored in the business card 50 or credit card 51 attached to the contact IC card reader 7 and writes information to them. The contact IC card controller IC8 also serves as a determination means for determining whether the business card 50 or credit card 51 is attached to the contact IC card reader 7. The contact IC card controller IC8 reads and writes information between the business card 50 or credit card 51 and the business card 50 or credit card 51 via the contacts 52 of the business card 50 or credit card 51.

The button 9 is a physical key (also called a physical key) provided for operating the handheld terminal 100, and is provided directly below the liquid crystal touch panel 11 as shown in FIG. 2. The key controller IC 10 is a controller IC that controls the button 9. When the business card 50 is removed from the contact IC card reader 7 of the handheld terminal 100, the function of the button 9 to operate the handheld terminal 100 is restricted.

In other words, if the business card 50 is not inserted in the contact IC card reader 7 of the handheld terminal 100, the conductor cannot operate the handheld terminal 100. If the business card 50 is inserted in the contact IC card reader 7 of the handheld terminal 100, the conductor can operate the handheld terminal 100. Also, if a credit card 51 is inserted in the contact IC card reader 7 of the handheld terminal 100, passengers can perform input operations related to payment processing, but the acceptance of other operations is restricted.

The liquid crystal touch panel 11 is a component that combines a liquid crystal panel that constitutes a display device and a touch pad that constitutes a position input device. The liquid crystal touch panel 11 is an input device that operates the handheld terminal 100 by pressing the display on the screen.

The LCD/TP controller IC 12 is a controller IC that controls the LCD touch panel 11.

The communication unit 13 is an interface unit that realizes at least one of the communication functions of, for example, a wide area network (WAN), a wireless local area network (WLAN), or Bluetooth (registered trademark). The communication-related circuit 14 is an interface circuit that complies with each standard for realizing the connection of the communication unit 13. The communication unit 13 and the communication-related circuit 14 can be applied to both wireless and wired communication. In this embodiment, wireless communication is assumed as an example. As shown in FIG. 2, the communication unit 13 connects the handheld terminal 100 to a payment server 301 via a wireless base station 200.

Battery 15 is a secondary battery that converts electrical energy into chemical energy, stores it, and converts it back to electrical energy when needed.

The PMIC 16 is a power management IC that combines the necessary power supplies according to the handheld terminal 100 being used, controls the power startup sequence according to the handheld terminal 100, and controls the power ON/OFF to reduce power consumption.

The NFC communication unit 17 is a communication unit that performs wireless communication at close ranges of within a dozen centimeters. The NFC communication unit 17 can transmit predetermined data related to payment at a speed of several hundred kbps between a contactless IC card at close range, and executes payment processing by charging the contactless IC card with an amount in advance. The NFC communication controller IC 18 is a controller IC for controlling the NFC communication unit 17.

The magnetic card reading unit 19 is a reading unit that reads data from a magnetic card. The magnetic card controller IC 20 is a controller IC that controls the magnetic card reading unit 19 that reads data from a credit card 51.

Note that the NFC communication unit 17, the NFC communication controller IC 18, the magnetic card reading unit 19, and the magnetic card controller IC 20 are optional components.

When a "business person" operates the handheld terminal 100 for business purposes, the business card 50 is inserted into the contact IC card reader 7. The SoC 1 of the handheld terminal 100 recognizes that the business card 50 is inserted and indicates that the terminal is "currently being used for business purposes," and allows the necessary business applications and button 9 input. The business card 50 is a first authentication key that controls the execution of business-related applications.

The behavior when this business card 50 is removed is predetermined. For example, when the screen transitions to the payment screen, if the business card 50 is removed from the contact IC card reader 7, the SoC 1 allows the passenger to perform the payment process.

During the payment process, the SoC1 of the handheld terminal 100 displays a message on the screen requesting the user to insert the credit card 51. The SoC1 connects to a payment center (see, for example, server 301 in FIG. 2) based on the information in the credit card 51, requests the user to enter a PIN as a process required for payment, and executes the payment process if the PIN is entered correctly. When the payment process is complete, the SoC1 displays a message on the screen requesting the user to remove the credit card 51.

In other words, in the payment process, SoC1 allows only the insertion and removal of credit card 51 and PIN input as terminal operations, and prohibits input using button 9. Note that input using button 9 may be permitted if necessary. If the "business person" is required to continue business, the "business person" can resume business by inserting business card 50.

The wireless base station 200 shown in FIG. 2 receives radio waves transmitted from the communication unit 13 of the handheld terminal 100 and converts the received radio waves into a signal. The wireless base station 200 then transmits the converted signal to the payment server 301.

In this embodiment, server 301 represents a payment server, and executes payment processing in response to requests from handheld terminal 100 via wireless base station 200.

<Payment terminal lock control>
Next, the settlement process executed by the handheld terminal 100 will be described with reference to the flowcharts shown in Figures 3A to 3C. Figures 3A to 3C are flowcharts showing the process in which the SoC 1 of the handheld terminal 100 according to the present embodiment settles the credit card 51.

The handheld terminal 100 is stored or charged with the business card 50 removed from the contact IC card reader 7. When the conductor uses the handheld terminal 100 for business purposes, the conductor turns on the power of the handheld terminal 100. This causes the SoC 1 to display a guidance screen 36 (see FIG. 4A) on the liquid crystal touch panel 11, instructing the conductor to insert the business card 50.

Figure 4A shows a guidance screen 36 displayed on the liquid crystal touch panel 11, instructing the conductor to insert a business card 50. This guidance screen 36 displays "Please insert your business card." The conductor follows this guidance and inserts the business card 50 into the contact IC card reader 7. This starts the series of processes shown in Figures 3A to 3C.

The handheld terminal 100 used by the conductor has various business applications (hereinafter referred to as business apps) pre-installed. When the business card 50 is inserted into the contact IC card reader 7 (Yes in step S001), the SoC1 displays a selection screen 30 (Figure 4B) on the liquid crystal touch panel 11, allowing the conductor to select each business app to be used for business (step S002).

Figure 4B shows a state in which the business card 50 is inserted into the handheld terminal 100 and the business application selection screen 30 is displayed on the liquid crystal touch panel 11. Specifically, this selection screen 30 displays a time information button 305, a ticket issue button 302, a translation button 303, and a route information button 304.

Returning to FIG. 3A, the explanation will continue. SoC1 determines the conductor's screen operation (step S003). If no screen operation has been performed (No in step S003), SoC1 repeats this screen operation determination process. When SoC1 detects a tap on the time information button 305 as a screen operation, it starts a time information application, and when it detects a tap on the ticket issue button 302, it starts a ticket issue application and proceeds to step S004. When SoC1 detects a tap on the translation button 303, it starts a translation application, and when it detects a tap on the route information button 304, it starts a route information application. In this embodiment, a case where the ticket issue application is launched by tapping the ticket issue button 302 will be described.

The ticketing app is an application program that allows the conductor to issue tickets on the train when a passenger has traveled beyond their destination or has forgotten to buy a ticket. The ticketing app requires payment processing for purchasing tickets, and is linked to the payment function of the handheld terminal 100.

SoC1 accepts the input of ticket issuance information (step S004). Ticket issuance information includes the departure station, arrival station, train type, and seat type. Specifically, SoC1 accepts the input of "Shinjuku" as the departure station information and "Tachikawa" as the arrival station information. SoC1 then accepts the input of "local" as the train type and "unreserved seat" as the seat type. SoC1 then displays the payment selection screen 31 shown in Figure 4C on the LCD touch panel 11 (step S005).

Figure 4C shows the state when the business card 50 is inserted into the handheld terminal 100 and the payment selection screen 31 of the ticket issuing app is displayed on the LCD touch panel 11. As shown in Figure 4C, the payment selection screen 31 displays the fare from "Shinjuku" to "Tachikawa" as "2,000 yen", with a cash button 311 and a card button 312 displayed below it. When the cash button 311 is tapped, cash is selected as the payment method for the fare. When the card button 312 is tapped, a credit card 51 is selected as the payment method for the fare.

Returning to FIG. 3A, if the passenger tells the conductor that they will be paying with a credit card 51, the conductor taps the card button 312 on the payment selection screen 31 to select credit card payment (Card in step S006). If the passenger tells the conductor that they will be paying with cash, the conductor taps the cash button 311 on the payment selection screen 31 to select cash payment (Cash in step S006). Here, as the card button 312 on the payment selection screen 31 is tapped, the SoC 1 displays a guidance screen 32 (see FIG. 4D) instructing the passenger to remove the business card 50 attached to the contact IC card reader 7.

Figure 4D shows the state when the business card 50 is attached to the handheld terminal 100 and a guidance screen 32 is displayed on the liquid crystal touch panel 11, instructing the conductor to remove the business card 50 from the contact IC card reader 7. As shown in Figure 4D, the guidance screen 32 displays the guidance "Please remove the business card." Following this guidance, the conductor removes the business card 50 from the contact IC card reader 7 of the handheld terminal 100 and hands the handheld terminal 100 to the passenger. Note that when the business card 50 is removed from the contact IC card reader 7, the handheld terminal 100 accepts input operations related to the payment process by the ticket issuing app and does not accept any other operations.

In other words, when the business card 50 is attached to the contact IC card reader 7 and payment processing by the ticket issuing app is started, if the contact IC card controller IC8 determines that the business card 50 has been removed from the contact IC card reader 7, SoC1 (restriction means) restricts the acceptance of operations other than input operations related to payment processing by the ticket issuing app.

In this case, even if the passenger operates the handheld terminal 100 from which the business card 50 has been removed, only input operations related to the payment process by the ticket issuing application are accepted, and operations of other business applications are not accepted. In this way, the SoC1 of this embodiment can prevent accidental operations on the handheld terminal 100 by passengers.

Returning to FIG. 3A, the explanation will continue. SoC1 determines whether or not the business card 50 has been removed from the contact IC card reader 7 (step S007). If the business card 50 has been removed from the contact IC card reader 7 (Yes in step S007), SoC1 proceeds to step S009 in FIG. 3B and displays a guidance screen 33 (see FIG. 5A) on the liquid crystal touch panel 11, instructing the user to insert the credit card 51 into the contact IC card reader 7.

Figure 5A is a diagram showing a state in which a guidance screen 33 is displayed on the liquid crystal touch panel 11 of the handheld terminal 100, instructing the user to insert a credit card 51 into the contact IC card reader 7. As shown in Figure 5A, the guidance screen 33 displays the message "Please insert your card."

Here, when the contact IC card controller IC8 determines that the credit card 51 is inserted into the contact IC card reader 7, the SoC1 restricts the acceptance of operations other than input operations related to the payment processing by the ticket issuing app. In other words, the handy terminal 100 only accepts input operations related to the payment processing by the ticket issuing app. Here, the SoC1 of the handy terminal 100 enables input operations related to the payment processing by the ticket issuing app and disables operations by the button 9 (physical key).

Figure 5B shows the state in which the guidance screen 33 is displayed on the LCD touch panel 11 of the handheld terminal 100, and the insertion operation of the credit card 51.

Following this guidance, the passenger inserts the credit card 51 into the contact IC card reader 7 of the handheld terminal 100. Here, the credit card 51 is a second authentication key for restricting the acceptance of operations other than input operations related to the payment process.

Proceeding to step S011 in FIG. 3B, when the credit card 51 is inserted into the contact IC card reader 7 (Yes in step S011), the SoC 1 establishes communication with the payment server 301. When communication with the payment server 301 is established, the SoC 1 displays a PIN (Personal Identification Number) input screen 34 (see FIG. 5C) on the LCD touch panel 11 (step S013).

Figure 5C shows the state when a credit card 51 is inserted into the handheld terminal 100 and the PIN entry screen 34 is displayed on the liquid crystal touch panel 11. As shown in Figure 5C, the PIN entry screen 34 displays "￥2,000" in the amount field 341, and below that, a numeric keypad 342 is displayed with the words "Please enter your PIN." The passenger taps the numeric keypad 342 to enter their PIN, and the payment is authenticated.

Returning to FIG. 3B for further explanation, when the passenger enters the PIN, SoC1 authenticates the payment using the PIN and determines whether the payment process has been completed (step S015). When the payment process is completed (Yes in step S015), SoC1 displays the payment completion screen 35 (see FIG. 5D) shown in FIG. 5D (step S017).

Figure 5D shows the state in which a credit card 51 is inserted into the handheld terminal 100 and a payment completion screen 35 is displayed on the LCD touch panel 11. As shown in Figure 5D, the payment completion screen 35 displays "Payment Complete."

In the present embodiment, as an example, the passenger inputs a PIN into the handheld terminal 100 for authentication, but this is not limited to this. For example, the handheld terminal 100 may acquire passenger information using a magnetic card and a signature to perform payment processing, or may execute payment processing using a contactless IC card. Furthermore, the handheld terminal 100 may execute processing to execute payment by inputting a signature on the liquid crystal touch panel 11.

Returning to FIG. 3B, the explanation continues. SoC1 displays a guidance screen 36 (see FIG. 5E) instructing the user to remove the credit card 51 from the contact IC card reader 7 (step S019), and proceeds to step S021 in FIG. 3C.

Figure 5E shows the state in which a guidance screen 36 is displayed on the liquid crystal touch panel 11 of the handheld terminal 100, instructing the passenger to remove the credit card 51, and the operation of removing the credit card 51. As shown in Figure 5E, the guidance screen 36 displays "Please remove your card." The passenger follows this guidance, removes the credit card 51 from the contact IC card reader 7 of the handheld terminal 100, and returns the handheld terminal 100 to the conductor.

As shown in FIG. 3C, the SoC1 determines whether or not the credit card 51 has been removed from the contact IC card reader 7 (step S021). If the credit card 51 has been removed from the contact IC card reader 7 (Yes in step S021), the SoC1 displays a guidance screen 36 (see FIG. 6A) on the liquid crystal touch panel 11 to prompt the user to insert the business card 50 (step S023).

Figure 6A shows a guidance screen 36 displayed on the liquid crystal touch panel 11 of the handheld terminal 100, which prompts the conductor to insert the business card 50. The guidance screen 36 displays "Please insert your business card." Following this guidance, the conductor inserts the business card 50 into the contact IC card reader 7 of the handheld terminal 100.

At this point, the SoC1 determines through the contact IC card controller IC8 that the business card 50 is attached to the contact IC card reader 7, and resumes accepting operations other than input operations related to the payment process by the ticket issuing app. In other words, the business card 50 is a first authentication key that resumes accepting operations other than input operations related to the payment process.

Returning to FIG. 3C, the SoC1 of the handheld terminal 100 determines whether or not the business card 50 has been inserted (step S024). If the business card 50 has been inserted into the contact IC card reader 7 (Yes in step S024), the SoC1 displays a screen 37 (see FIG. 6B) including a ticket issue button 371 (step S025). This ticket issue button 371 is for launching a ticket issue application.

Figure 6B is a diagram showing a screen 37 including a ticket issue button 371 displayed on the liquid crystal touch panel 11 of the handheld terminal 100. As shown in Figure 6B, when the ticket issue button 371 is tapped, the SoC 1 issues a ticket and ends the series of ticket issuing processes.

As described above, the SoC1 of the handheld terminal 100 according to this embodiment restricts the acceptance of operations other than input operations related to the payment processing by the ticket issuing app when the business card 50 is attached to the contact IC card reader 7 and the payment processing by the ticket issuing app is started, and then the contact IC card controller IC8 determines that the business card 50 has been removed from the contact IC card reader 7.

The conductor can then hand the handheld terminal 100 to the passenger and have them make payment using the credit card 51.

To be more specific, if the conductor were to hand over a handheld terminal used for work to a passenger, there would be a risk that the passenger may inadvertently operate the terminal. For this reason, the conductor does not want to hand over the handheld terminal to the passenger in order to prevent inadvertent operation of the terminal. On the other hand, if the passenger were to hand over their credit card to the conductor, who is a stranger they have never met before, there would be a risk that the credit card would be misused.

Therefore, when the business card 50 is removed from the contact IC card reader 7, the handheld terminal 100 according to this embodiment restricts the acceptance of any operations other than input operations related to the payment operation. The conductor can remove the business card 50 and hand the handheld terminal 100 to a passenger. At the same time, the passenger can use the handheld terminal 100 handed to them by the conductor to carry out the payment process without having to hand over the credit card 51 to the conductor.

(Modification)
The above-described embodiment of the present invention is presented as an example, and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the present invention. For example, the following are included.

In this embodiment, the application of payment processing using a ticket issuing app has been described as the predetermined processing, but this embodiment is not limited to payment processing. For example, some business terminals used for home delivery services and the like are operated in such a way that the touch panel of the terminal is used to have the customer sign for receipt. This signature is done by the customer, and the same problems as in the above embodiment arise.

Therefore, in the modified example, when the business card is inserted into the business terminal, operation of each business-related function is permitted. Then, when the business card is removed from the contact IC card reader of the business terminal, input of a signature indicating receipt of a parcel or the like is permitted, and other operations are prohibited, thereby preventing accidental operations by customers.

In addition, in this embodiment, the handheld terminal 100 is configured to accept the input of a PIN, but this is not limited to a PIN and may be, for example, a password. In addition, if a password is used, it may be authenticated by the payment server 301.

These embodiments and their variations are within the scope and spirit of the invention, and are included in the scope of the invention and its equivalents described in the claims.
