The present invention relates to a traffic card and a payment method using a USB (USB) and RFID (RFID) chip.

More specifically, a USB card is provided on the transportation card to charge the rechargeable battery built in the transportation card, and also the Internet can be charged and charged, and a passive RFID chip can be used. The present invention relates to a traffic card and a payment method that can be used more efficiently by providing a function of turning on / off an active RFID chip.

In general, transportation cards are widely used as a means of payment for all public transportation, including buses and subways, and they can also be used for authentication, microfinance payments, cash receipts, and use of cards. have.

As transportation cards such as T-money recently emerged, various additional services using the transportation cards have been proposed one after another, providing a discount on transfers to passengers using the transportation cards and mileage through cooperation with various point service companies. To earn and use.

However, the charge of the transportation card should be used at a designated place of a bus stop or at a ticket office in a subway station, and the current balance can only be checked after use, and the user cannot pay with a transportation card. I have a discomfort. In particular, in order to charge the transportation card, the hassle of visiting the charging station with the transportation card charging terminal or the ATM (Automatic Teller Machine) equipped with the transportation card charging function and the electronic payment using the transportation card are proposed. Therefore, when the customer uses the e-commerce, if the amount charged on the transportation card is smaller than the payment amount, there is a problem that the customer should visit the charging station directly.

On the other hand, traffic cards are popularized, and traffic cards with various additional service functions other than the conventional transportation fee payment function have been developed and distributed, and many technical approaches for adding such additional functions have been made.

In particular, as a technology to perform a variety of additional functions by embedding the USB (RF) and RF (RF) chips in electronic money, Korean Patent Publication No. 10-2002-0048926 (filed: June 5, 2002, name of the invention A payment method using electronic money combining USB and RF chip has been proposed.
