Description

[Detailed description of the invention] The present invention relates to a card with increased added value.

Calculators in recent years have become ultra-thin and have added functions such as a clock function, making them more useful and portable. In addition, its thickness gradually becomes thinner and more flexible, starting from 0.5 mm.
They can now be made to a size of about 2mm, allowing them to be carried around with business cards, banknotes, etc.

On the other hand, the use of cashless cards is gradually becoming more common, and people begin to carry around a large number of cash cards, credit cards, etc., and as they become thicker, they become more difficult to carry around. Or, you may forget a necessary card and carry an unnecessary card by mistake. You must also carry a train pass, etc. separately.

In view of the above-mentioned points, the present invention provides a card that allows password data and transaction amount to be input from the card, and also allows the current amount to be displayed on the card. Fig. 1 is a perspective view of a watch and an alarm card CD according to an embodiment of the present invention, where LC is a liquid crystal display, KB is a keyboard, and AL is an alarm, and has approximately the same thickness as a cash card or credit card. and flexibility. In FIG. 2, the back side is provided with a code section M using magnetic ink or other well-known technology to identify the owner, similar to a cash card or credit card. This M part is the third
It is decoded by the head part RH of the reading device R as shown in the figure, and at the same time from the keyboard KB to the terminals C1 and C.
2, H1, H2, etc., give the reading device R information known only to the owner. This makes it possible to identify the card owner and prevent unauthorized use. If the reader R recognizes it correctly, the cash will be paid if it is a cash card. At this time, you can also input the payment amount using the keyboard KB. In addition, when using a credit card, the user can input the amount needed at that time from the keyboard KB and deduct it from the current deposit amount storage memory in the card CD, allowing the user to check the current amount at any time by operating the memory recall key. preferable. It can also be applied to commuter passes, employee ID cards, driver's licenses, etc. FIG. 4 shows an example of a cash card which is not specially provided with the section M shown in FIG. 2 and is configured to read display contents from a liquid crystal display LC. When the card CD is loaded into the reading device R of a cash dispensing machine at a bank, etc., and the user enters the encrypted code such as the date of birth on the keyboard KB and other necessary key operations, the reading device R detects the card insertion or key operation. Then turn on the lamp L and read the contents on the reflective or transmissive liquid crystal display LC. Further, the next key operation etc. will be notified by a well-known interactive display DSP or the like. In the same way as above, enter the payment amount using the key KB, and confirm that the various conditions are satisfied by the CPU shown in Figure 5.
If approved, pay the requested amount. At this time, the current payment amount is input from the deposit balance storage memory in the calculator circuit CAL to the terminals C1, C2, H1,
The CPU deducts it via H2 etc. Therefore, the balance can be easily checked as described above, and if the withdrawal amount is over, the alarm AL is activated to warn you. This alarm may be activated when the subscription period approaches. In the case of a commuter pass, load the card according to this example into the reader at the automatic commuter issue office, insert the required amount into the currency reader, and then CAL until the next validity period.
Update the memory contents in.

At this time, a specific encryption key operation is also performed. The card is inserted into the station's automatic pass recognition device, and when recognition is completed through simple key operations, the CPU opens the gate for a set period of time and allows the user to pass. This usage can also be applied to identification cards and the like.
