On or Off Card / Transportation card

The transportation card with On/Off function enables the users to turn on and off the RFID Tag function at their own discretion.
The various types of cards in a wallet equipped with the RFID Tag function can be overlapped and occur payment errors. So the users may pay the fare unintentionally.
In addition, it can cause problems such as leak of personal information with the use of RFID Tag.
In order to solve these issues, by separating induction coil (antenna) from the microchip inside the card, the users can use the RFID Tag function on only one card that users want to use in time.
