Embodiment Construction

[0036] The technical solutions of the present invention will be described below in conjunction with examples, as will be described, as described in Examples of the present invention, not all of the embodiments of the invention. Based on the embodiments of the present invention, there are all other embodiments obtained without making creative labor without making creative labor premises.

[0037] like Figure 1-2 As shown, a card reader that does not communicate with the mobile NFC module, including:

[0038] RF module 10, which is used for coding, modulation, demodulation, and decoding of RF signals;

[0039] The oscillator module 20 is electrically connected to the radio frequency module 10 for providing a working clock to the radio frequency module 10, and outputting the carrier frequency of the RF module deviates from the value range of the carrier frequency used by the NFC communication;

[0040] Antenna module, the antenna module is electrically connected to the radiofrequency...

Abstract

The invention provides the card reader which does not communicate with the NFC module of the mobile phone. The method comprises: a radio frequency module used for coding, modulating, demodulating and decoding a radio frequency signal; an oscillator module, wherein the oscillator module is electrically connected with the radio frequency module and is used for providing a working clock for the radio frequency module and enabling the output carrier frequency of the radio frequency module to deviate from the carrier frequency used by NFC for a certain numerical range; and an antenna module, wherein the antenna module is electrically connected with the radio frequency module, and the antenna module is used for converting the radio frequency signal into a magnetic field required by near field communication and communicating with a non-contact smart card through magnetic field coupling. The card reader not communicated with the mobile phone NFC module solves the problem that in the prior art, when a card reader reads a card, unexpected data communication is carried out between the card reader and the mobile phone NFC module.

Description

Technical field [0001] The present invention relates to the technical field of non-contact smart card read-write equipment, in particular, to a card reader and a card reader method that is not communicating with the mobile NFC module. Background technique [0002] With the popularity of NFC phones, more and more people use mobile phone NFC functions instead of applications such as traditional bus cards, bring 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 work and travel. At present, there is a large number of safety inspection equipment in the airport and train station, which typically requires a number of inspections such as metal detection, ID card reading, a combination and ticket inspection. When the NFC function of the mobile phone is turned on, when the phone is non-contact card reader with a microcarrier frequency of 13.56MHz, the NFC module of the phone will be activated and com...
