Near Field Communication (NFC) is an emerging technology. Devices using NFC technology (such as mobile phones) can exchange data when they are close to each other. It is a non-contact It evolved from the integration of radio frequency identification (RFID) and interconnection technology. By integrating the functions of inductive card reader, inductive card and point-to-point communication on a single chip, mobile terminals are used to realize mobile payment, electronic ticketing, access control, Mobile identity recognition, anti-counterfeiting and other applications.

The application of NFC security is mainly to virtualize mobile phones into access control cards, electronic tickets, etc. The NFC virtual access card is to write the existing access card data to the NFC of the mobile phone. In this way, the access control function can be realized using the mobile phone without using a smart card. This is not only very convenient for the configuration, monitoring and modification of the access control, but also enables remote modification. and configuration, such as temporary distribution of voucher cards when needed, etc. The application of NFC virtual electronic tickets is that after the user purchases the ticket, the ticketing system sends the ticket information to the mobile phone. The mobile phone with NFC function can virtualize the ticket information into an electronic ticket, and just swipe the phone directly when checking the ticket. The application of NFC in security systems is an important area of ??NFC application in the future, and the prospects are very broad. Because this field can directly bring economic benefits to users of the technology, giving them more incentive to upgrade existing equipment and technology. Because the use of mobile phone virtual cards can reduce the use of access cards or magnetic card tickets, directly reducing usage costs, it can also appropriately increase the degree of automation, reduce personnel costs and improve efficiency.
