In the processing device, after payment processing by card,
The judgment means for judging whether or not the data writing to the card is normally completed, the card invalidation processing means for invalidating the card when it is judged that there is an abnormality, and the invalidation processing means. At least the balance data after payment processing of the invalidated card is printed on the receipt paper together with the card number of the invalidated card, and a card invalidation receipt issuing means for issuing as a card invalidation receipt separately from the purchase receipt is provided. It is a thing.

[Operation] If the product sales data processing device has such a configuration,
When payment by a card occurs, the amount of payment is reduced from the balance data of the card, and the rest is written in the card as new balance data. Here, if an error occurs during the writing of the balance data and the data is not accurately written to the card, the card is ejected from the card reader / writer as an invalid card. Also,
The balance data to be written on the card is printed on the receipt together with the card number and issued as a card invalid receipt. Therefore, even if an error occurs when writing the balance data to the card, the payment by the card is treated as valid and there is no need to redo. At this time, the card is invalidated and disposed of, but the balance of the card is printed on the receipt and is compensated.

When the flag F1 is reset to "0", an error occurs because the payment by the prepaid card is instructed even though the prepaid card 3 is not inserted in the card reader / writer 2.

On the other hand, when the card insertion flag F1 is set to "1", the payment by the prepaid card 3 inserted in the card reader / writer 2 is instructed, so the flag F1 is reset to "0". Later, total amount memory 42
And the balance of the prepaid card 3 is compared. Here, if the balance is insufficient with respect to the total amount, it is an error because payment is impossible.

On the other hand, when the balance is equal to or more than the total amount of money, payment is possible, and the total amount is printed as a card payment amount on a receipt or the like. Then, the receipt is issued. Further, the total amount of money is subtracted from the balance of the prepaid card 3 to obtain new balance data after payment processing, and the new balance data is stored in the card data buffer 43. And the curdley writer 2
Then, the new balance data in the card data buffer 43 is sent out to instruct to write to the prepaid card 3. As a result, in the card reader / writer 2, the balance data after the payment process is written in the prepaid card 3.

After that, the CPU 31 confirms whether or not the balance data is normally written in the prepaid card 3.

(Judgment Means) Then, when the data is normally written, a card ejection command is sent to the card reader / writer 2, and this processing is ended. As a result, the prepaid card 3 is ejected from the card insertion / removal opening 11 of the card reader / writer 2.

On the other hand, when the balance data is not normally written in the prepaid card 3, an instruction to invalidate the card 3 is sent to the card reader / writer 2. As a result, in the card reader / writer 2, a hole is punched at a predetermined position of the card 3 to invalidate the card 3.

(Card invalidation processing unit) Further, the CPU 31 drives and controls the printer 9 to print the stored contents of the card data buffer 43, that is, the balance data and the card number read from the prepaid card 3 and the new balance data after the payment process on the receipt. Output and issue the receipt as a card invalid receipt. (Card invalid receipt issuing means) After that, a card ejection command is issued to the card reader / writer 2.
To end the process. As a result, the invalid prepaid card 3 is ejected from the card insertion / ejection slot 11 of the card reader / writer 2.

In this embodiment having such a configuration, when a customer offers to pay with the prepaid card 3, after registering all the products purchased by the customer, the prepaid card 3 brought by the customer is carded to the card reader / writer 2. Insert the card from the insertion / removal opening 11 and key in the card key 26. Here, when the balance of the prepaid card 3 is equal to or more than the total amount of money of the customer, the total amount of money of the customer is reduced from the balance of the prepaid card 3 to complete the payment. Then, for example, a normal purchase receipt 51 shown in FIG. 7 is issued. Also,
The balance data after the payment process is written in the prepaid card 3 by the card reader / writer 3 and discharged from the card insertion / ejection slot 11. However, when the balance data is not normally written due to some abnormality during the writing of the balance data, the card is invalidated and punched and then ejected. At this time, the printer 9 prints on the receipt the card number of the card 3, the balance data before the payment process (read balance), and the balance data after the payment process (new balance). For example, the card invalid receipt shown in FIG. Issued as 52. Ie receipt
From the new balance of 52, it becomes possible to grasp the balance data that should be originally written in the card 3. Therefore, the store side compensates the balance of the invalidated card by paying the customer with cash commensurate with the new balance. In addition, the store side is a card invalid receipt
52 will be attached to the applicable card and the compensation amount will be charged to the card issuing company.

As described above, according to this embodiment, even if the balance data after the payment processing is not normally written to the card due to some abnormality after the payment by the prepaid card 3 is processed, the payment is still made. Can be treated as valid. At this time, the card becomes invalid, but since the card invalidation receipt 52 on which the balance of the card is printed is automatically issued, the balance of the card can be surely compensated.

Although the card number, the reading balance and the new balance are printed on the card invalid receipt in the above embodiment, the effect of the present invention can be obtained by printing out at least the card number and the new balance. As an example of a method for invalidating a card, a case in which a hole is punched in a card is shown, but the method is not limited to this. For example, a printing mechanism may be provided in the card reader / writer 3 to print the fact that the card is invalid. Good. In addition, it goes without saying that various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] As described in detail above, according to the present invention, even if an abnormality occurs after processing the payment by the card, the payment can be treated as valid, and the payment processing for the card that has become abnormal. It is possible to provide a product sales data processing device capable of issuing a card invalidation receipt that can surely compensate for the balance afterwards.
