Abstract

PURPOSE:To eliminate the necessity of using an exclusive card reader/writer from the card system by providing an inputting means for inputting data, displaying means for displaying data, controlling section for processing data, and data transmitting means which transmits and receives data to and from other systems in a non-contact state. CONSTITUTION:The controlling section of a card 1 correlates a preset password code with an inputted password code and, when they coincide with each other, makes a coincidence display on the displaying section 1b of the card. When they do not coincide with each other, the controlling section makes a suitable display on the section 1b and, at the same time, transmits radio waves to the card 2 held by a store clerk. The radio waves transmitted from the card 1 are received by the card 2 and the controlling section of the card 2 judges the password code correlated result. When the correlated result is coincident, the store clerk inputs the amount of purchased goods to the card 2 by using the key inputting section 2a of the card 2. Accordingly, the amount is displayed on the displaying section 2b of the card 2 and, at the same time, radio waves are transmitted from the card 2 and the same amount is also displayed on the displaying section 1b of the card 1. Therefore, no special card reader/ writer is required.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a card such as an ATM card that allows monetary information to be exchanged between cards, and a card system using the same. [Technology] Fig. 3 is a schematic diagram showing the mode of information transmission and reception by a conventional contactless card system, in which 21 is a contactless card;
2 indicates a card reader/writer. The contactless card 21 stores personal data and the like, and is carried by the individual. On the other hand, the card reader/writer 22 includes a key input section 22a that can input commands, data, etc., and a display section 22 for displaying data, etc.
b, and installed in stores, etc. Then, between the card league writer 22 and the contactless card 21, when the card league writer 22 inputs the processing details through its key human power section 22a, the card league writer 22 commands the contactless card 21 via radio waves. , send data. Upon receiving the command, the contactless card 21 performs predetermined processing and sends the processing results to the card reader/writer 22 again via radio waves.

The card reader/writer 22 performs predetermined processing based on the result, and displays the processing result on the display section 22b.

FIG. 4 is a flowchart showing the process of carrying out cashless shopping using the conventional contactless card system described above.

A card reader/writer 22 is installed in the store, and personal data such as the amount of money and a password is stored in the card 21 owned by the individual. When a product is purchased, the purchaser's personal identification code is input into the card 21 using a card league writer 22 via radio waves. The card 21 checks the input PIN code with the PIN code manually generated in advance to confirm whether the cart in question belongs to the purchaser (
Step Tl).

If the card 21 is not suitable, the card 21 is returned, and if the card is suitable, the purchase price is input into the card reader/writer 22, and the display part 22b and the display part 21 of the card 21 are displayed.
b (step T2).

Step T3) to judge whether the displayed amount is appropriate or not.
If it is inappropriate, the purchase is canceled (step T4), and if it is appropriate, the amount of the purchased item is subtracted from the balance on the card 2I (step T5).

[Problem to be solved by the invention]

By the way, with such a conventional contactless cart system, it is necessary to install a cart league/writer at each store, and it cannot be used in stores that do not have a card reader/writer installed.

The problem was that the number of stores was limited.

The present invention was created in view of the above circumstances, and its purpose is to eliminate the need for a dedicated cart league writer, reduce costs, and enable transactions between cards without being restricted by location or time. The purpose of this invention is to provide a card and a card system using the card.

[Failure to solve the problem]

In the card according to the present invention and the cart system using the same, each card is provided with a data input means, a data display means, and a data transmission means for transmitting and receiving data, and data is transmitted and received between the plurality of cards.

[Effect]

According to the present invention, it is thereby possible to transmit, receive, and process data between cards while mutually confirming each other.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on drawings showing embodiments thereof.

FIG. 1 is a schematic diagram showing an aspect of data transmission and reception by a card system using a cart according to the present invention.
2 indicates a card. Each card 1.2 has the same structure and includes a key input section 1a, 2a, a display section 1b, 2b, and a data storage section (not shown), a control section, and a mutual communication between the two cards 1.2. It is now possible to send and receive information between the two in a non-contact manner, for example by radio waves.

FIG. 2 is a flowchart showing the process of cashless shopping using both cards 1 and 2 described above. For example, assume that Card 1 is held by an individual and Card 2 is held by a clerk.

First, at the time of purchase, a product purchaser inputs his or her personal identification code into the card 1 that he/she owns using the key input section 1a.

The control section of the card 1 checks the preset password code and the input password code, and if they match, displays a match, and if they do not match, displays a corresponding display on the display section 1b, and A radio wave is oscillated toward the card 2 owned by the clerk (step SL). The radio wave oscillated from the card 1 is received by the card 2, and its control section judges the result of the verification of the PIN code (step S2). If there is a mismatch, the transmission and reception of monetary information ends. If they match, the clerk enters the purchase price on the card 2 using the key input section 2a. As a result, the amount is displayed on the display section 2b of the card 2 (step S3), and the amount is displayed on the display section 2b of the card 2.
A radio wave is emitted from the card 1, and the same amount is displayed on the display section 1b of the card 1 (step S4).

The purchaser determines whether the amount displayed on the display section 1b of his/her card 1 is appropriate (Step S5), and if it is inappropriate, cancels the purchase (Step S6); Display section 1 from the balance entered in the storage section
Decrease the amount displayed on b, while the clerk holds card 2.
The amount displayed on the display section 2b is added to the balance input in the storage section at (step S7). This means that the transaction between the product purchaser and the store clerk is completed.

In the above embodiment, a case has been described in which radio waves are used as a means of transmitting information between the cards 1 and 2, but light or sound waves (including ultrasonic waves) may also be used.

In addition, in the above embodiment, data is transmitted and received between cards 1 and 2 in a non-contact manner, but it is possible to transmit and receive data between cards 1 and 2 in a non-contact manner. It goes without saying that it is also possible to send and receive data in a non-contact manner.

〔Effect of the invention〕

As described above, in the system of the present invention, data entered on cards can be exchanged between cards, so a special card reader/writer is not required, equipment costs are low, and transactions are simple and accurate. The present invention exhibits excellent effects such as being made possible.
