摘要： A near field communication device includes an antenna, a matching circuit connected to the antenna, a clock extraction block that extracts a clock from a signal received by the antenna and outputs the extracted clock, a frequency compensation block that compensates for a frequency of the extracted clock and outputs a compensated clock, and a modulation and amplification block that performs modulation and amplification by using the compensated clock and outputs a transmit signal to the matching circuit. A first extracted clock has a first frequency that is extracted when the transmit signal is not output and a second extracted clock has a second frequency that is extracted when the transmit signal is output, the frequency compensation block compensates for the second frequency of the second extracted clock based on a difference between the first frequency of the first extracted clock and the second frequency of the second extracted clock.

摘要： 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.
