NFC applications can generally be divided into four basic types:
1, contact completed. For applications such as access control or traffic/activity ticket inspection, users only need to put the device with the ticket or access control code near the card reader. It is generally used for gate locking devices in residential areas or buses and subways.
2. Contact and confirmation. For applications such as mobile payment, users must enter a password to confirm the transaction, or just accept the transaction. Generally used in shopping malls and other scenes that need to be paid.
3. Contact and contact. Linking two NFC-enabled devices can realize peer-to-peer network data transmission, such as downloading music, exchanging images or synchronously processing address books.
4. Contact and explore. NFC devices may provide more than one function, and consumers can explore the functions of devices and understand the potential functions and services of NFC devices.
