Abstract
The invention provides a non-contact-outage card reader. The non-contact-outage card reader comprises an MCU, an outage control chip and a non-contact type radio frequency chip, wherein the outage control chip is connected with the MCU and the non-contact type radio frequency chip is connected with the MCU and the outage control chip. A radio frequency module generating a magnetic field is arranged in the non-contact type radio frequency chip. The non-contact type radio frequency chip is used for conducting data communication with a non-contact type intelligent card. The MCU is used for sending an outage control signal to the outage control chip. The outage control chip is used for controlling the radio frequency module in the non-contact type radio frequency chip to power down when the outage control signal sent by the MCU is received, so that the magnetic field generated by the radio frequency module disappears, and data communication between the non-contact type radio frequency chip and the non-contact type intelligent card is interrupted.
