Abstract
A wireless communication device for detecting a card may include a signal generating circuit that generates a power signal for supplying a first power to a card, first communication signals for communicating with the card based on the first power, and a second communication signal for communicating with the card based on a second power supplied to the card, and a detecting circuit that detects a response signal received from the card, when the first communication signals or the second communication signal is output to the card. The signal generating circuit generates the first communication signals and the second communication signal such that the second power is supplied to the card by the first communication signals or the second communication signal.
