摘要:
A device and method are provided. The device includes a controller, a memory, and a transceiver. The controller generates authentication information based on a user input to the device. The memory stores the generated authentication information. The transceiver receives authentication information, which is generated by a point of sale (POS) terminal based on a user input to the POS terminal, from the POS terminal, when the device enters within a predetermined range from the POS terminal. The controller compares the generated authentication information with the received authentication information, and provides card information which is used in a transaction with respect to an item or a service to the POS terminal based on a result of the comparison.
