RFID technology can easily sense or read data through a non-contact method, which has led to many identity recognition-related applications. Not only that, RFID has also derived a short-range wireless communication technology NFC (Near Field Communication). The technical principle of NFC is mainly to transfer data and communicate in a point-to-point manner, that is two electronic devices can communicate as long as they are within a few centimeters of each other. Therefore, NFC has now been extended to many application fields. NFC-enabled devices can act as digital wallets, ID cards and key cards.

With the development of NFC technology, mobile payment has become a mainstream. Now you can buy things without using cash and make mobile payment directly with your mobile phone, which brings great convenience to people and greatly shortens the checkout time. In addition, in the public transportation vehicles that people now use, mobile phones with NFC functions can also be used as electronic tickets. Payment can be made through the mobile phone, and it also has a stored value function, which is very convenient and time-saving.
