Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a card system for identifying a customer by a card number stored for each card.

(b) Summary of the invention The card system according to the present invention issues a card with a different number for each card to the customer, and in the card system that identifies the customer with this card number, issues multiple cards to the same customer. When doing (when updating a card or reissuing a defective card), the card number of the previous card (first card) is stored in the old number storage area of the new card (second card). The card processing device identifies the customer by this number when the old number is stored. This makes it easy to identify a customer even when a plurality of cards are issued to the same customer, and eliminates the need to rewrite files.

(c) Conventional Technology In a general card system, a holder such as a customer is identified by an individual number set for each card. In order to avoid duplication of card numbers in such a card system, there is a system in which the card number is stored in advance in the card before issuance, and also in the system in which the card number is stored when the card is issued, the predetermined number is Some systems are forcibly stored.

(d) Problems to be solved by the invention However, in such a card system, when a customer loses the card, the card becomes defective, or when the card is renewed, the No. (2 or more cards) will be issued, but the new card number will be stored in the reissued card, so the number that identifies the customer will change. There is a problem that post-processing such as rewriting becomes complicated.

The present invention has been made in view of such problems,
An object of the present invention is to provide a card system which solves the above problems by storing the number of the first card in the subsequent cards and performing the subsequent processing with this number.

(e) Means for Solving Problems This invention is for issuing a card to a card processing device in a card system in which the card is individually identified by the card number or the old number. A means for registering the card number of the card as customer identification data, and a means for storing the card number of an already issued card as an old number in the old number storage area of a newly issued card when the card is reissued. And a means for identifying the customer by the card number of the card when receiving the card,
Means for identifying a customer with the old number instead of the card number when the old number is stored in the old number storage area of the card.

(f) Action The card used in the card system of the present invention has a card number individually assigned to each card stored (pre-encoded) in advance, and further has an old number storage area. On the other hand, when issuing a card to a customer for the first time, the card processing device registers the card number of the card as customer identification data. Thereafter, the card processing device identifies the customer based on the customer identification data. When the card is reissued to the customer, the card number of the old card is stored as the old card number in the old number storage area of the newly issued card. When accepting a card issued in this way, as a general rule, the customer is identified by the card number of the card, and when the old number is stored in the old number storage area, the customer is identified by this old number instead of the card number. Identify.

As described above, the card number is pre-encoded, which simplifies card issuing and registration work, and when reissuing a card, the old number is continuously used to manage customers. Ensures.

(g) Embodiment FIG. 2 is an external view of a card reader used in a card stamp system according to an embodiment of the present invention. The card reader 1 is a device which is connected to the POS terminal device 2 and operates in conjunction therewith. A card insertion slot 3 into which a later-described saver card is inserted is provided on the front surface of the card reader 1. Data such as the purchase amount of the customer is transmitted from the POS terminal device 2 to the card reader 1, and the saver card data is transmitted from the card reader 1 to the POS terminal device 2 and printed / displayed.

This card stamp system is a system designed to promote sales at retail stores, and is as follows. The retail store issues a saver card (see FIG. 4) to the customer. The retail store cumulatively stores the stamp number data in the saver card for each predetermined purchase amount of the customer. This storage is performed by the card reader. When the cumulative value of the stamp number data reaches a predetermined value, the customer can exchange it for a voucher or a product.

FIG. 3 shows a block diagram of the control unit of the card reader.
The controller 10 for controlling the operation includes a CPU 10a, a memory 10b, an I / O control unit 10d connected to an operation unit of a card reader, an interface 10e connected to the POS terminal device, and a power supply unit 1 for supplying power to these.
It consists of 0f. Further, the card reader unit 11 connected to the I / O control unit 10d is a card reader 11a for reading / writing magnetic data of the card and a card punch mechanism 11b for punching a used card.
It consists of

The POS terminal device 2 connected via the interface has a controller 20, a keyboard 21 and a printer 22, and further has a display, a cash box opening / closing device and the like. This POS terminal device is connected online with a host computer.

FIGS. 4 (A) and 4 (B) show a schematic structure of a saver card used in this card reader. This saver card is a card that the customer possesses and cumulatively stores the stamp number data according to the purchase amount as described above. FIG. 3A is a plan view of the saver card. This card is PET
A magnetic stripe portion 31 is formed on the back surface of the card. The magnetic stripe portion 31 stores the data shown in FIG. Of these, the card number is stored in advance before the card issuance. This card number is also pre-printed on the card surface (32).

In the same figure (B), the magnetic stripe section 31 has a company identification code (33) for identifying the company that controls this system.
Is a card identification code (34) for storing that the card is a saver card, a member store code (35) for identifying the member store that issued this card, a card number (36), a cumulative number (37) and an old number (38). ) Is stored in the area.

The operation of the control unit of the card reader will be described with reference to the flowchart of FIG.

FIG. 7A is a flowchart showing the main operation. When the saver card is inserted at n1, the card data is read (n2) and it is determined whether the old number is stored (n3). If the old number is stored, that number is set as the customer number (n4), and if the old number is not stored, the card number of the card is set as the customer number (n5). Next, the purchase amount is received from the POS terminal device, converted into stamp number data (n7), and card data is written (n8). If this writing is done normally, these data are sent to the center via the POS terminal and stored in a file (n10), the journal is printed (n11), and then the card is ejected (n
12) End the operation.

When the writing of the card data is not normally performed, it is determined that the card is defective, and the card reissue operation (n14) is performed. When issuing a saver card to the first customer, a new card issuing operation (n1

FIG. 7B shows the new card issuing operation. When a new card is inserted at n20, the pre-encoded data (card number) of the card is read (n21). Necessary items such as the customer's name are input by the attendant (n22). This input is performed by key operation or the like. Required data of the input data is encoded in the magnetic stripe portion of the card (n23), and these data are transmitted to the center via the POS terminal device (n24) and the process returns. The center sets up a new data area for this customer.

FIG. 7C shows the card reissue operation. First, at n30, the defective card is ejected. Next, when a staff member inserts a new card (n31), the pre-encoded card number is read (n32). After the data read from the defective card is stored in this card (n33), the process returns. In this storing operation, the customer number set in n4 or n5 is stored as the old number.

n33 corresponds to the "means for storing the card number of the first card in the old number storage area of the second card" of this invention, and n3 and n4 are the "card numbers when the old number was stored" of this invention. Regardless of the old number ".

(h) Effect of the Invention As described above, according to the present invention, data such as a card number is pre-encoded on a card, and by registering this card number as customer identification data, when issuing a card, Issuing a card is easy. In addition, even if multiple cards are issued to the same customer, the card number of the first issued card can be stored as the old number in the cards issued later, and this number can be used to identify the customer. Therefore, a plurality of customer numbers do not exist for one customer, and customer management / file management can be facilitated. As a result, customer management does not become complicated even if a card in which card numbers are stored and printed in advance to eliminate duplication of card numbers is used.
