Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an IC in which an integrated circuit is built into a plastic card.
Concerning the components of the card.

[Conventional technology]

Conventionally, this type of IC card generally has a module consisting of a microcomputer chip and a memory chip built into a plastic card, and is used to write data,
It was possible to record, read, and erase.

[Problem that the invention seeks to solve]

In the conventional IC card mentioned above, the data to be written,
The recorded data and read data are only stored as electrical signals in the built-in integrated circuit, and the IC card user cannot check the contents without special equipment such as an IC card reader. There wasn't. For example, I.C.
When the card is used for shopping cards, telephone cards, etc., there is a drawback in that the user cannot check the remaining balance.

The present invention provides an IC card that allows the entire contents stored on the IC card to be confirmed without any special equipment.

[Means for solving problems]

The IC card of the present invention is a card in which an integrated circuit chip is built into a plastic card, in which data can be written.
an electric circuit or an integrated circuit that can be recorded, read out, and erased;
The IC card is characterized by having a display section capable of displaying the written data, recorded data, and read data, and an input means section for displaying necessary data on the display section.

〔Example〕

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment of the present invention.

In Fig. 1, the integrated circuit chip f2 built into the plastic card body l has a terminal 2a on the front side of the plastic card body 1, and has a data writing device and a data reading device (
(none of which are shown) allows data to be input and output.

A display section 3 capable of displaying data is arranged and built-in on the surface side of the glass card main body 10 so that the displayed contents can be viewed visually.

A personal identification number input means 4 for displaying necessary data on the display section 3 is further disposed and built into the front side of the plastic card body 1.

Note that arrow A indicates the direction in which the IC card is inserted into the data writing machine and data reading machine (not shown).

An example of the use of the IC card of this embodiment configured as described above will be described.

For example, when an IC card such as a telephone card is purchased by a user, the amount of money that can be purchased with the card is recorded as an electrical signal in the built-in integrated circuit chip f2. When displaying and confirming the recorded remaining amount, enter the PIN number known only to the user who registered in advance at the time of IC card purchase from the input means section 4, and the recorded remaining amount will be displayed on the display section 3. It is possible to confirm this by

Note that although the explanation of this embodiment requires a built-in power supply for driving an electric circuit and an electric circuit, the explanation is not added in the embodiment of the present invention as it is a well-known matter.

〔Effect of the invention〕

As explained above, the present invention provides an IC card in which an integrated circuit chip is built into a glass card, which includes a display section capable of displaying written data, recorded data, and read data, and a password input means section for displaying the data. By having a card, for example, it is possible to display the remaining balance of a telephone card or shopping curve, and use the card appropriately.It can also be used as a substitute for a passbook at banks, etc., so users can use it without a passbook. There is no need to check extra slips during transactions, and the practical effect is excellent.
