Integration of Access Control System and NFC Technology Promotes the Development of Mobile Access Co

With the development of science and technology, access control system is not only wireless, but with the evolution of the times and the application of NFC technology, it is gradually developing in the direction of virtualization and mobility. Mobile access control will stand on the stage of history. Near field communication (NFC), also referred to as short-range communication or near-field communication, is a set of communication protocol that allows two electronic devices (one of which is usually a mobile device, such as a smart phone) to communicate within a few centimeters. NFC, like the electronic ticket smart card in the past, will allow mobile payment to replace or support such systems. NFC is used on social networks to share contact information, photos, movies or files. NFC enabled devices can act as electronic ID cards and key cards. NFC provides easy to set up low-speed connections and can also be used to guide more capable wireless connections. The integration of NFC technology and access control system is mainly reflected in hardware and software: Hardware: by upgrading the identification front end of access control system (i.e. card reader), NFC chip is required in the access control reader / lock. When it senses NFC mobile phone, NFC chip will release a password to the card reader at the front end of access control system, and then control the electronic motor, Let the electronic motor open or close the door lock. In terms of software, we should also consider making full use of the characteristics of NFC handheld devices. We should write NFC access control instructions into the mobile phone to realize the functions of air authorization of access control authority, mobile phone dialing to open the door, reservation access, access control information query, mobile phone deployment and removal. The advantage of the access control system based on NFC is that the cardholder is more convenient to carry and the information is more secure, and NFC technology can realize more personalized functions through mobile app.
