Method and system for automatically and quickly switching NFC (Near Field Communication) access control card

Abstract

According to the NFC access control card automatic rapid switching system provided by the invention, through the arrangement of the induction receiving module, the simulation card switching module, the simulation card library module and the judgment module, when a user approaches NFC equipment to access control equipment every time, a radio frequency field is automatically identified through the induction receiving module, and an automatic rotation mode is started; the simulation card switching module continuously switches the NFC simulation card information in the simulation card library module in sequence, and the feedback signal is identified through the judgment module after each switching, so that the system does not need to manually select an access control card in advance; a radio frequency field can be automatically identified, NFC simulation card information can be automatically rotated and switched to be identified by a card reader until the correct NFC simulation card is identified, the whole rotation process is rapid, the theoretical time is not longer than 0.5 second, the speed is far higher than the speed of manually selecting an access control card, use is convenient, manual intervention is not needed, and the problem that the card swiping experience is poor is solved.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a method and system for automatic and fast switching of NFC access control cards. Background technique [0002] Near field communication, also known as NFC, is a short-range wireless communication technology that allows non-contact point-to-point data transmission and data exchange between devices. NFC has three application modes: card reader mode, card simulation mode and Point-to-point mode, the most widely used is the card simulation mode, which can make the mobile terminal with NFC function (such as mobile phone, wristband, etc.) simulate a non-contact card to be recognized by the card reader, so as to carry out mobile payment There are many types of cards that can be simulated by NFC, such as bus cards, bank cards, and access control cards. However, due to too many types of NFC cards bound by users, it is necessary to pre-register the NFC card when entering and exiting acce...

[0002] Near field communication, also known as NFC, is a short-distance wireless communication technology that allows non-contact point-to-point data transmission and data exchange between devices. NFC has three application modes: card reader mode, card simulation mode and Point-to-point mode, the most widely used is the card simulation mode, which can make the mobile terminal with NFC function (such as mobile phone, wristband, etc.) simulate a non-contact card to be recognized by the card reader, so as to carry out mobile payment There are many types of cards that can be simulated by NFC, such as bus cards, bank cards, and access control cards. However, due to too many types of NFC cards bound by users, it is necessary to pre-register the NFC card when entering and exiting access control. Select the type, set it as the access control NFC card, and then perform the access control card swiping operation. This operation is cumbersome and requires manual intervention, which reduces the convenience of experience. Therefore, how to enable users who bind multiple NFC cards to use access control Automatically jumping to the NFC access control card has become an existing problem that needs to be solved urgently
