For example, the computing unit (not shown) may exchange the wireless reader with the personal information and the small payment information to perform the public transportation cost payment, and store the total sum of the public transportation expenses paid after summing in units of a predetermined period (for example, one month). It can be stored in the (not shown) to be settled for the public transportation cost of a predetermined period unit.

The wireless antenna 130 is electrically connected to the IC chip 120 when the elastic switch 140 is shorted to enable wireless transmission and reception of data between the IC chip 120 and an external wireless reader.

The elastic switch 140 is contracted or deformed according to a user's operation to electrically connect the IC chip 120 and the wireless antenna 130 for a predetermined time (for example, 2 seconds) so that the IC chip 120 is connected to the wireless antenna 130. And transmit and receive data to and from the wireless reader, and after a predetermined time is restored to a circular shape by elasticity to open the IC chip 120 and the wireless reader, and disconnects data transmission and reception with the wireless reader. For example, if the elastic switch 140 sets the predetermined time for activating the contactless card with a switch to 24 hours, the user can operate the elastic switch 140 of the contactless card once in the morning to use the desired card all day long. .
