And a display unit 4 for displaying the output of the information output unit 8 on a screen
It is composed of

The highest digit of all credit cards stores a logical value "1" as a start code. The next digit following the start code is an ID identifying whether the credit card is of a bank or credit sales company type
In the example of FIG. 2, the value a is stored.
The next digit following the ID code is called a business type code, and is a code added by a credit card issuing company according to each standard. Hereinafter, a series of codes from the most significant digit to the third most significant digit are collectively referred to as a key code. Every credit card has such a key code.

In the card information shown in FIG. 2, 9532 which is a credit company code represented by four digits starting from the fourth digit counting from the highest order including this key code is stored next to the key code. Then, the membership number 3540025, which is represented by seven digits, and the expiration date of the credit card, which is represented by six digits, 91090
4 is stored.

The information table storage unit 5 shown in FIG.
As shown in FIG. 3, the information table which can be stored in the information table includes, for each key code, a credit company code, member number information, expiration date and card name in association with the key code. Is stored. In the storage area of the credit company code, the digit position indicating the first digit of this credit company code from the most significant digit, the number of digits, and the value of the credit company code itself are represented by “,” in this order. In the storage area of the member number information, the most significant digit position of the member number and the number of digits are stored in this order with ",".

[0013] The expiration date is also stored under the same rules as the membership number information. The card name storage area stores the card name value as it is.

In FIG. 3, the storage area of the credit company code whose key code is 1a9 is 4,4,95.
32 is stored, 8, 7 are stored in the storage area of the member number information, and 15, 6 are written in the storage area of the expiration date.

That is, the credit company code is represented by a four-digit numerical value starting from the fourth digit from the highest digit of the credit card, and indicates that the value is 9532. It indicates that it is represented by a 6-digit numerical value starting from the 15th digit counted from the highest order.

[0016] However, some credit cards having the same key code have different credit company codes. Therefore, if there is a credit card having a different credit company code, the same key code is used. Information on a credit card having another credit company code corresponding to the code is stored in the information table illustrated in FIG.

For a credit card whose key code matches the credit company code, the name of the credit card can be specified.

The information stored in the credit card is read by the card reading means 1, and the read information is temporarily stored in the card information storage unit 2.

As the card reading means 1, a commonly used card reader may be used.

It is assumed that the card information read by the card reading means 1 has the contents shown in FIG. The card information storage unit 2 outputs the input information to the information comparison unit 6. When this information is input to the information comparison unit 6, a key code is read from the input information, a predetermined read signal associated with the key code is output, and the read signal is added to the information table reading unit 3. The information table reading unit 3 receives the read signal, and
The information stored in association with the corresponding key code is output to the read information comparison unit 6. The information comparing unit 6 is configured to output information corresponding to the specified number of digits from the specified digit position based on the credit company code information in the information output from the information table reading unit 3 for the information output by the card information storage unit 2. The read value and the value of the credit company code output from the information table reading unit 3 are compared, and if they match, the member number to be extracted and the digit position and the number of digits of the expiration date are respectively entered into the information table reading unit. The information table reading unit 3 reads out the card name from the information input from the information table 3 and outputs the card name to the display information extracting unit 7.

If the two do not match, the read signal is output from the information comparing section 6 until the two match. When these pieces of information are output to the display information extraction unit 7, the display information extraction unit 7 reads out the membership number and the expiration date from the card information storage unit 2 based on the input information, and The information is output to the information output unit 8 together with the name. When the information is input to the information output unit 8, the information is edited in a predetermined format and output to the display unit 4. The display unit 4 displays the input information on a screen.

As is apparent from the above description, the information table storage unit 5 stores what kind of card name the card information read by the card reading means 1 is from a credit card. Since the information and the information are specified by being compared by the information comparing section 6, the necessary information such as the credit name, the membership number, and the expiration date can be read from the card information and displayed on the display section 4. .

In FIG. 1, if a printer which receives an output of the information output unit 8 as an input in parallel with the display unit 4 is connected,
Necessary information can be printed on paper.

[0024]

As described above, the credit card information extracting apparatus according to the present invention uses the key code for the information indicating the information storage location for such a credit card even if the desired information storage locations are different from each other. An information table stored for each credit card and each credit company code is prepared, and the information comparison unit compares the information read from the credit card with the information in this information table to identify the credit card name read out from the credit card. However, there is an effect that desired information can be extracted and displayed quickly without requiring the judgment of the operator. In addition, as compared with the conventional case where a credit card operator reads information displayed on the surface of a credit card, there is an effect that the chance of reading an incorrect value can be reduced.
