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.

Abstract: An electronic device includes a clock recovery circuit, a converter circuit, and a decoder circuit. The clock recovery circuit generates a reference clock. The converter circuit generates a conversion value that corresponds to a difference between a phase of reception data and a phase of the reference clock. The decoder circuit analyzes a reception characteristic of an antenna based on conversion values that corresponds to a start-of-frame (SOF) marker. The decoder circuit decodes a conversion value that corresponds to encoded data following the SOF marker in the reception data, with reference to the analyzed reception characteristic, into a digital value.

Abstract: A communication circuit chip includes a controller, a power manager, and a memory. The controller selectively communicates, based on a reception signal that is received through an antenna, with one memory card among first and second memory cards. The power manager transfers power, in response to receiving the reception signal through the antenna, to the one memory card that is selected to communicate with the controller. The memory stores content data such that content of data stored in each of the first and second memory cards is recognized. The controller selects the one memory card that is to communicate with the controller from among the first and second memory cards, with reference to the stored content data.

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.
