Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a product sales data processing device such as an electronic cash register or a POS (Point of Sales). More specifically, the present invention relates to a product sales data processing device that allows payment using a prepaid card.

``Prior Art J'' Product sales data processing devices such as electronic cash registers and PO8 terminals are known to allow payments to be made using prepaid cards.

Conventionally, this type of product sales data processing device registers all the products that a customer wants to purchase, and then, when the subtotal key is pressed, checks whether a prepaid card is inserted or not, and then checks whether a prepaid card is inserted or not. If the prepaid card is inserted, the subtotal amount is subtracted from the remaining amount of the prepaid card, and payment with the prepaid card is possible on the condition that the difference is 0 or more.

[Problem to be solved by the invention] However, in conventional product sales data processing devices, the remaining balance of the prepaid card is checked at the end, so it is necessary to register all the products before checking the total purchase price or the prepaid card balance. It is not possible to check whether the remaining amount is sufficient.

Therefore, if the remaining amount is insufficient, a customer who does not have or has little cash on hand may request to return one of the products that have already been registered.

In such a case, the operator must return the product, which takes time.

In particular, if the remaining amount is significantly short of the total amount purchased, many items will be returned, and the return process will take time, resulting in the next customer having to wait for a long time.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a product sales data processing device that solves these conventional problems and allows the remaining amount of a prepaid card to be checked every time an IWj product is registered.

[Means for Solving the Problems] Therefore, in the present invention, an input means for inputting data regarding a product, a read/write means for reading the balance from a prepaid card and writing the balance to the prepaid card, a balance memory and a subtotal are provided. a storage means having a memory, a notification means, and each time data regarding the product is input from the input means, on the condition that the balance read out from the prepaid card by the read/write means is stored in the balance memory; , a registration means for adding the amount of the product to the subtotal memory; and a registering means that adds the amount of the product to the subtotal memory, and a difference amount obtained by subtracting the total amount of the subtotal memory from the remaining amount of the remaining amount memory. The system comprises a checking means for checking whether the difference is larger than a predetermined amount, and a notification execution means for causing the notification means to notify that when the checking means checks that the difference is not larger than the predetermined amount. It is characterized by

Therefore, each time data related to a product is entered, the remaining amount is checked, and when it is no longer greater than a predetermined amount, a notification is issued to that effect, allowing the operator and the customer to know that the remaining amount is insufficient or low. . Therefore, the customer can decide whether to purchase the remaining products depending on the amount of cash he/she has and the state of possession of other prepaid cards, thereby reducing the number of return operations.

[Operation] First, the remaining amount of the prepaid card held by a regular customer is read by the reading/writing means and stored in the remaining amount memory. In this state, when data regarding a product is input from the input means, the amount of the product is added to the subtotal memory.

At this time, it is checked whether the difference obtained by subtracting the total amount in the subtotal memory from the remaining amount in the remaining amount memory is greater than a predetermined amount, for example, zero. As a result, if it is checked that the difference is not larger than a predetermined amount, the notifying means will notify that fact.
