Conventionally, an IC card in which an integrated circuit is built in a card substrate is formed in a standard 54 mm vertical and 86 mm horizontal dimension like a generally used credit card, and data is read by a card reader / writer. You can read and write. In recent years, non-contact type IC cards that can read and write data using an induction electromagnetic field as a transmission medium have been developed. For example, a card reader / writer is provided at an entrance / exit gate and the non-contact type IC card is held over. Systems that open and close the gate are also being studied. On the other hand, portable electronic devices such as cellular phones are becoming lighter and smaller and can transmit and receive data as well as voice communications, and are widely used by many people.

A small electronic card unit 12 having a built-in module 14 is partitioned and formed so as to be cut out, and can be used alone as a non-contact type standard IC card. The cut out small electronic card unit 12 is a mobile phone provided with an antenna coil. It can be used by being mounted on a portable electronic device such as the above or a card adapter 20 described in detail later.
[0015]
The card substrate 11 is, for example, an insulating substrate made of a plastic plate material such as hard vinyl chloride formed into a rectangular plate having a standardized size similar to that of a credit card or the like and a dimension of 54 mm in length and 86 mm in width. A loop-shaped antenna coil 13 suitable for transmitting and receiving data using an induction electromagnetic field as a transmission medium is formed on the peripheral edge side of the surface by etching or the like, and the peripheral-side area in which the antenna coil 13 is formed For example, a small card area 12a of the small electronic card portion 12 having a notch 18 at one corner with a size and shape of about 20 mm in length and 25 mm in width is formed on the predetermined surface except for the card substrate 11 so as to be cut out from the card substrate 11.

Since it is not as small as that, there is no need to worry about losing it. Further, the small card area 12a is pushed out with a finger, cut off at the cutting margin 16 and cut out from the card substrate 11, and the small electronic card section 12 is attached to a portable electronic device such as a cellular phone provided with an antenna coil and is contactless. It can be used as an IC card, enables data transmission / reception with a portable electronic device, and can be displayed on a display or the like provided in the portable electronic device. The cutting margin 16 is formed in a taper shape, and when the small electronic card portion 12 is cut out from the card substrate 11, the cutting margin 16 is not left on the peripheral edge of the small card area 12a.
