how to use nfc

NFC is a wireless connection technology that provides easy, safe and fast communication. Its transmission range is smaller than that of RFID. The transmission range of RFID can reach several meters or even tens of meters. However, due to the unique signal attenuation technology adopted by NFC, it is relatively For RFID, NFC has the characteristics of short distance, high bandwidth, and low energy consumption. Second, NFC is compatible with existing contactless smart card technology and has now become an official standard supported by more and more major manufacturers. Again, NFC is a short-range connection protocol that provides easy, secure, fast and automatic communication between various devices. Compared to other connection methods in the wireless world, NFC is a close-proximity method of private communication. Finally, RFID is more used in production, logistics, tracking, and asset management, while NFC is used in access control, public transportation, and mobile phones.
It plays a huge role in the fields of payment and so on.
Now the emerging NFC mobile phone has a built-in NFC chip, which forms part of the RFID module and can be used as an RFID passive tag—to pay for fees; it can also be used as an RFID reader—for data exchange and collection. NFC technology supports a variety of applications, including mobile payments and transactions, peer-to-peer communications, and on-the-go information access. Through NFC mobile phones, people can connect with the entertainment services and transactions they want to complete payments, obtain poster information and more through any device, anywhere, at any time. NFC devices can be used as contactless smart cards, smart card reader terminals and device-to-device data transmission links. Its applications can be divided into the following four basic types: for payment and ticket purchase, for electronic tickets, For intelligent media and for exchanging and transmitting data.
