Many people use credit cards as they, while using credit cards, do not need to carry cash, can check usage details easily, can receive benefits such as accumulated money from credit card companies, and can receive various tax benefits. Recently, a credit card with an IC chip which is more difficult to copy and securer than a credit card with magnetic material is widely used, so users can use credit cards without worries. Thanks to an RF device, the users can use the credit cards conveniently without getting the credit cards out of a wallet. However, a current credit card is made of a thin plastic material and has a certain size, so there is a possibility of damage and it is inconvenient as the users have to carry the credit card in a wallet. Furthermore, in case of a device on which a credit card is mounted such as a hi-pass terminal, the size of the device cannot be reduced any more due to the size of a credit card even if the device itself can be smaller. The present invention relates to a small credit card instead of the credit card using the thin plastic material in a certain size. According to the present invention, as the volume of the credit card is reduced, the user easily carries the credit card. The credit card is not likely to be damaged, and is easily mounted on other devices. |
