Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC card conversion adapter device (IC: integrated circuit), and more particularly, to an IC card for using a contact type IC card in a reader / writer device for a non-contact type IC card. It relates to a conversion adapter device.

[0002]

2. Description of the Related Art Conventionally, contact type IC cards and non-contact type IC cards
The card can be used only by a dedicated reader / writer device, and the communication protocols applied to both cards are completely incompatible.

It is fully anticipated that there will be requests to do so.

In order to cope with this, it is obvious that two types of interfaces, one for contact and the other for non-contact, need not be employed as in the above-mentioned combination card. It is only necessary to obtain a new technical configuration for enabling use in the / writer device.

The main objects to be solved by the present invention are as follows.

That is, a first object of the present invention is to provide an IC card conversion adapter capable of using a contact type IC card such as a money card in a reader / writer device for a non-contact type IC card such as an IC telephone card. No device is provided.

A second object of the present invention is to provide an IC card conversion adapter device having additional functions such as a calculation function.

A third object of the present invention is to provide an IC card conversion adapter device capable of inserting and using a slot mounting member in a card slot of a reader / writer device for a non-contact type IC card. It is.
