And a server 10 that is a management device connected via the network.

  Here, a store or the like refers to a customer or a member through a member card 8 which is an electronic card, in addition to a place that provides a product or service such as a restaurant or restaurant that sells products. ID is assigned to the card, and the card ID is used to show the general location where the customer or member can be grasped.

  The membership card 8 is an electronic card in which an IC chip is incorporated. The member card 8 stores information for each customer such as a card ID. Specific examples of the electronic card include an IC card, an NFC (Near Field Communication) card, an RFID (Radio Frequency IDentification) card, and a magnetic stripe card. Although FIG. 1 shows a single member card 8 that does not have other functions, for example, the customer terminal 30 itself may have a function as an electronic card. In addition to electronic cards that can only be used at specific stores, etc., they also include cards that can be used in common at various stores and services, and are not limited by the location or use. .

  The base terminal 20 is a device that can read the card ID of the member card 8 possessed by the customer in a contact or non-contact manner. In the example shown in FIG. 1, the base terminal 20 includes the cash register device 22 and the card reader 24. Has been. The base terminal 20 is connected via a telecommunication line 5 to a server 10 that is a management device described later. In FIG. 1, the base terminal 20 is composed of a cash register device 22 and a card reader 24. However, the present invention is not limited to this mode. In addition to reading the card ID of the customer's membership card 8, there are functions described later. If it is a means which can perform, it will not be restrict | limited by the form.

  The customer-side terminal 30 is an electronic portable terminal such as a mobile phone, a smartphone, or a PDA, and is a device that can transmit an e-mail. Further, the customer side terminal 30 is not limited to a portable terminal, and may be an electronic device such as a customer's home or office personal computer. If the customer side terminal 30 has a function that can be operated by the customer and can send and receive e-mails, the customer side terminal 30 is limited depending on its form. It doesn't let you.

  The customer e-mail address is an e-mail address that the customer desires to register, and may be an e-mail address that can be transmitted and received by a personal computer in addition to an e-mail address of an electronic portable terminal such as a mobile phone, a smartphone, or a PDA.

  The telecommunication line 5 is, for example, a complex such as an Internet network or a mobile phone network. Actually, for example, the base terminal 20 is directly connected to the Internet network, whereas the customer side terminal 30 is connected to the Internet network via the mobile phone network, and the base terminal 20 is also a customer as a whole. Both of the side terminals 30 are connected to the server 10 via the telecommunication line 5, but are individually connected to the server 10 via another route of the telecommunication line 5.

  The management device is a control unit that is connected to the base terminal 20 and the customer-side terminal 30 via the telecommunications line 5 and controls the entire system that stores and manages the customer mail address and the like of the customer-side terminal 30. Server 10. The server 10 is an example of a management device, and can control the exchange with the telecommunications line 5 and store / manage customer mail addresses and the like in one device. The functions can be realized by separate devices, and are not limited by the form.

  Next, the operation of the customer mail address acquisition system 1 configured as described above will be described with reference to the drawings. In the following description of this embodiment, the reference numerals in parentheses correspond to the reference numerals in FIG.

  First, the customer holds the member card 8 possessed by the customer over the card reader 24 of the base terminal 20 in the store, and the base terminal 20 acquires the card ID of the member card 8 using the card reader 24 (S100). Next, the base terminal 20 uses the acquired card ID, the lead time that is the time when the card ID was acquired, and the base terminal ID of the base terminal 20 to indicate time stamp data (described as “TimeStampData” in FIG. 2). Is generated (S101). Then, the base terminal 20 transmits the time stamp data to the server 10 that is a management apparatus via the telecommunication line 5.

  As shown in FIG. 2, in this embodiment, the data sent from the base terminal 20 to the server 10 includes a base terminal ID and a lead time in addition to the card ID. These three data are time stamps. Although it is referred to as data, the time stamp data is composed of card ID and auxiliary data for associating a card ID and a customer mail address as will be described later. Here, the auxiliary data is composed of two pieces of data, that is, the base terminal ID and the lead time. However, the auxiliary data may be at least one arbitrary data, and may be composed of one, two, or more arbitrary data, and is not limited by the configuration or type of data. Absent.

  Next, the base terminal 20 generates a local part of a link mail address that is a destination mail address of an electronic mail that the customer side terminal 30 sends to the server 10 based on the time stamp data (S103). A link mail address is generated by connecting the host name indicating the server 10. Specifically, the base terminal 20 uses the lead time as a key and calculates a hash value from the base terminal ID, the card ID, and the lead time to generate a local part of the destination mail address. That is, as a general rule, the link mail address has the local part as the key + hash value, and after @, the host name indicates the server 10 (link mail address = key + hash value @ host name indicating the server 10). However, since the hash value is a bit string, it is not always an ASCII character that can be handled as a mail address, so that it can be handled as an electronic mail using a system conversion such as Base32 Encode.

  Then, the base terminal 20 delivers the link mail address to the customer side terminal 30 (S110). There are several possible methods for the base terminal 20 to pass the link mail address to the customer side terminal 30. For example, the base terminal 20 displays the barcode on the display of the cash register 22 of the base terminal 20 or prints the barcode with a printer. Then, the link mail address can be delivered to the customer side terminal 30 by reading the barcode on the customer side terminal 30 (S111). Also, the link mail address is displayed on the display of the cash register 22 of the base terminal 20 or printed by a printer, and the customer types the link mail address into the customer terminal 30, whereby the link mail address is changed to the customer terminal 30. (S112).

  Further, when the membership card 8 is integrated with the customer terminal 30, the card ID is read by holding the customer terminal 30 over the card reader 24. You may make it deliver a link mail address to the customer side terminal 30. FIG. Furthermore, for example, a link mail address is temporarily delivered to a mobile terminal such as a mobile phone possessed by the customer, and the link mail address is handed over from the mobile terminal to another customer side terminal, so that the customer finally wants to register. You may make it deliver a link mail address to the customer side terminal which can handle a customer mail address. Thus, the method by which the base terminal 20 delivers the link mail address to the final customer terminal 30 is not particularly limited.

  Next, the customer side terminal 30 sends an e-mail to the received link mail address using the customer mail address of the customer side terminal 30 itself (S201). This customer e-mail address is an e-mail address to be registered in the server 10 which is a management apparatus in association with the member card 8 used by the customer himself. The server 10 side is set to be able to receive all e-mails if the host name is addressed to itself. In this case as well, the local part of the link mail address is not defined on the server 10 side. The e-mail addressed to the link mail address from the customer terminal 30 can be received.

  The server 10 as the management apparatus calculates a key and a hash value from the time stamp data received from the base terminal 20. Specifically, the lead time received from the base terminal 20 is specified as a key, and the hash value is calculated from the base terminal ID, card ID, and lead time received from the base terminal 20 (S301). Then, the server 10 stores the lead time, hash value, card ID, etc. in a database in the server 10 (S302).

  Further, after receiving the electronic mail from the customer side terminal 30, the server 10 grasps the lead time and the hash value from the local part of the link mail address of the electronic mail received from the customer side terminal 30 (S311). Since the original key + hash value is an ASCII character that can be handled as an e-mail address using system conversion such as Base32 Encode, the key + hash value is restored, and the lead time and hash value that are keys are grasped. . Then, the server 10 stores the lead time, hash value, and sender email address in a database in the server 10 (S312).

  Next, the server 10 inquires the time stamp data received from the base terminal 20 and the contents of the local part of the destination mail address received from the customer side terminal 30, and associates the card ID with the customer mail address. The customer mail address of the customer who acquired the card ID at the base terminal 20 is acquired (S320). Specifically, the server 10 inquires the lead time and the hash value obtained from the base terminal 20 and the lead time and the hash value obtained from the information of the destination mail address from the customer side terminal 30, and each lead When the time and the hash value match, the server 10 acquires the customer's email address by associating the card ID obtained from the base terminal 20 with the customer email address.

  Even if there is a time difference between the acquisition of the time stamp data from the base terminal 20 and the reception of the e-mail from the customer side terminal 30 due to the status of the telecommunication line 5 in the server 10, Are stored in the server 10 (S302, S312), and then inquired for association (S320), so that no particular problem occurs.

  Also, the server 10 that is the management device determines the validity period of the link mail address that is the destination mail address from the lead time, and after the validity period has passed, the association between the card ID and the customer mail address is not performed. It is possible to prevent the association between the card ID and the customer mail address, which is unnecessary or illegal. In addition, it is possible to manage the validity period by incorporating the validity period of the link mail address in the key handled by the base terminal 20 or the server 10.

  According to the customer mail address acquisition system 1 configured as described above, the server 10 serving as a management apparatus receives the card ID and auxiliary data received from the base terminal 20 and the destination mail address received from the customer terminal 30. The customer wishes to register at the site terminal 20 because the customer's email address of the customer who obtained the card ID at the site terminal 20 is obtained by inquiring the contents of the local part and associating the card ID with the customer email address. The customer e-mail address can be acquired by the server 10 without knowing the customer e-mail address.

  Further, since the card ID and the customer mail address are associated with each other using the auxiliary data, particularly the lead time, it is possible to easily generate a variety of destination mail addresses and to easily prevent the destination mail addresses from being complicated. In addition, by using a hash function to generate a destination mail address, it becomes difficult to analogize information included in the destination mail address.

  As described above, according to the present invention, a customer email address acquisition method and a customer email address acquisition system capable of acquiring a customer email address with a management device without knowing the customer email address that the customer wants to register in the base terminal. Can be provided.
