Ideally, a mobile phone with NFC function can be used as a bank card to swipe the mobile phone on POS machines in supermarkets and shopping malls.
The third is the security field. NFC security applications are 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 into the NFC of the mobile phone, so that the access control function can be realized by 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 can be remotely modified. And configuration, such as temporarily distributing credential cards when needed. The application of NFC virtual electronic ticket 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 you can directly swipe the mobile phone during ticket checking.
