Abstract

PURPOSE:To read out required information from a cash card to display it on a display part by providing a connecting part capable of engaging or disengaging with the cash card incorporating an IC and a changeover switch of the circuit in the main body of an electronic calculator. CONSTITUTION:A connecting part 16 which can be engaged with and detached from an input/output terminal 3 of a cash card 1 is provided on the outside of an electronic calculator body 10. A changeover switch 17 is provided which switches the connection to an interface circuit in the body 10 to the connection to an interface circuit of the IC in the cash card 1. The card 1 is inserted to the connecting part 16 to connect the card terminal 3 to the electronic calculator, and the changeover switch 17 is turned off. The IC in the card 1 is connected electrically to a key input part 11 and a display part 12 on the electronic calculator side. Consequently, required information in the card is read out by the operation of key switches 11a... of the key input part 11 and is displayed on the display part 12.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an m-car that allows necessary information to be easily retrieved from cards such as cash cards that have a built-in f-conductor integrated circuit (hereinafter referred to as an IC). Personal cash cards and credit cards, etc., which are frequently used at banks etc.

The minimum necessary information such as a code number is recorded on a magnetic tape attached to a plastic card.

Recently, there has been an increasing need to write various types of information onto cards, but the amount of information that can be written on cards using magnetic tape is limited. ,,Also, combination 7., which has become a social problem in recent years. - It is also one of the factors that makes it easier to commit crime.

Therefore, a cash card with a built-in IC has been proposed in which the card 10 is built inside the card and information can be written to and read from the IC. According to such a cash card with a built-in IC, r c
A lot of information can be written in C's memory.2
It's convenient.

However, in not only conventional cash cards with magnetic tape attached, but also the above-mentioned cash cards with a built-in IC, writing, sending, and reading information to and from the cards was mostly done at the terminal equipment of the computer.

Therefore, even if a large IC card with a built-in IC card containing 8ffl of information is provided, each person who owns this card must have one copy in the card! Please write the information.

Don't read this out when you need it A7.
It is impossible for a woman to read the bank account balance information written on a terminal device.

Therefore, the present invention provides a cage with a built-in IC and an input/output terminal provided at the end of the card, which is already widely available on the market.
The main body of the rrl jp, which can be obtained in an attractive manner and at a low price, is equipped with a 14M connector of the cash card, a connection part that can be engaged with the 14M connector, and a 1-circuit relay change switch. Insert your cash card and turn the changeover switch. It works like a key button switch on a train (
