Abstract

The invention provides a card reader which does not communicate with the NFC module of the mobile phone. It includes: a radio frequency module, which is used for encoding, modulation, demodulation and decoding of radio frequency signals; an oscillator module, which is electrically connected to the radio frequency module, and is used to provide the radio frequency module with a working clock and make the radio frequency module output a carrier The numerical range of the frequency deviation from the carrier frequency used in NFC communication is 5%~30%; the antenna module, the antenna module is electrically connected to the radio frequency module, and the antenna module is used to convert the radio frequency signal into a near-field communication The required magnetic field and communicate with the contactless smart card through magnetic field coupling. The card reader that does not communicate with the NFC module of the mobile phone improves the problem in the prior art that the card reader performs undesired data communication with the NFC module of the mobile phone when reading a card.

Description

technical field [0001] The invention relates to the technical field of non-contact smart card reading and writing equipment, in particular to a card reader and a card reading method that do not communicate with a mobile phone NFC module. Background technique [0002] With the popularity of NFC mobile phones, more and more people use the NFC function of mobile phones to replace traditional applications such as bus cards, which brings more convenience to people's lives. At the same time, because of the needs of the current situation, in order to ensure the safety of people's work and travel. At present, places such as airports and railway stations are equipped with a large number of security inspection equipment, which usually require multiple inspections such as metal detection, ID card reading, combination of person and certificate, and ticket inspection for passing personnel. When the NFC function of the mobile phone is turned on, when the mobile phone is close to a non-co...
