Card reader for high-frequency wireless smart card

Abstract

The invention relates to a card reader for a high-frequency wireless smart card, which comprises an effective radio-frequency transceiving module and a shell and is provided with a radio-frequency signal shielding device and a radio-frequency interference module, wherein the radio-frequency signal shielding device is used for restricting the communication zone of the radio-frequency transceiving module and preventing radio-frequency interference signals from interfering with the communication zone; the radio-frequency interference module can interfere with radio-frequency signals of the same and adjacent frequency ranges; the radio-frequency signal shielding device is provided with a sensing window which faces the card reading surface of the card reader; the radio-frequency transceiving module is arranged in the shielding device; and the radio-frequency interference module is arranged in the shielding device. The invention has the advantages of simple structure, stable and reliable operation and the like, is easy to implement, can satisfy demands caused by unending changes of various terminals, effectively solves the problem of variable card swiping distance caused by different terminals, effectively control the distance, and can restrict the card swiping direction and region. The invention can be used for electronic wallets, mobile phone access control, mobile phone payment and the like.

Description

technical field [0001] The invention relates to the technical field of radio frequency communication, in particular to a card reading device for a high-frequency wireless smart card, especially a card reading device for radio frequency communication.
