Abstract
A card reader performing a wireless communication with a card includes a first pulse generation unit generating a first detection pulse for detecting the card, a second pulse generation unit generating a plurality of second detection pulses for detecting the card, or a plurality of communication pulses for communicating with the card, and a card detection unit for sensing a card being detected by the first detection pulse or the second detection pulses. In the case that the card is not sensed through the first detection pulse, the second pulse generation unit generates the second detection pulses using the communication pulses and senses the card using the second detection pulses.
