摘要： A method for controlling a resonance frequency of a near field communications (NFC) device that includes a resonance unit to transmit and receive data through electromagnetic waves and an NFC chip comprises the following steps: detecting whether an NFC card or NFC reader exists around the NFC device; setting a resonance frequency of the resonance unit as a first optimal frequency based on the magnitude of a voltage generated from the resonance unit while a carrier wave is radiated to the NFC card through the resonance unit when the NFC card is detected; and setting a resonance frequency of the resonance unit as a second optimal frequency based on at least one of the magnitude of a voltage generated from the resonance unit in response to an electromagnetic wave received from the NFC reader and the magnitude of an inner current generated from the NFC chip in response to the electromagnetic wave received from the NFC reader when the NFC reader is detected. The method can independently set a resonance frequency as an optimal frequency with respect to each of a reader mode and a card mode.

摘要： An RFID reader for offsetting transmission leakage signals is provided to reduce the whole power consumption by cancelling the transmission leakage current by the control of a digital unit. An RFID reader comprises a digital unit(370) which calculates the amplitude and phase of a transmission leakage signal, and stores the calculated result, and a leakage offsetting circuit(330) which generates a leakage offset signal in response to the control of the digital unit, wherein the leakage offset signal has the same amplitude as that of the transmission leakage signal and has a phase reverse to that of the transmission leakage signal. The leakage offsetting circuit receives a local oscillation signal from a frequency synthesizer(350), and then generates the leakage offset signal.

摘要： A device and a method for breaking information stored in an RFID(Radio Frequency IDentification) tag by using electric shock are provided to prevent infringement of privacy or copy of an article by breaking the RFID tag attached to the article with the electric shock over a threshold when the article is opened. An electric shock generator(210) breaks an RFID tag(220) by generating electric shock having a voltage level higher than a threshold. The shock generator generates the electric shock by using energy generated when an article is opened or closed, or using frictional force generated when the opening/closing part of the article is rotated if the RFID tag is included in an opening/closing part of the article. The electric shock generator breaks the RFID tag by destroying information stored in the RFID tag when the generated electric shock is applied to the RFID tag.
