What do you know about the NFC? If life is so useful, do you

Time:2018-08-03 / Popularity:

First of all, what is the NFC function? Let's get this straight.
NFC is also superior to infrared and Bluetooth transmission methods. As a consumer-oriented trading mechanism, NFC is faster, more reliable, and much simpler than infrared, and does not require strict alignment to transmit data.
Compared with Bluetooth, NFC is for close-range transactions and is suitable for the exchange of financial information or sensitive personal information and other important data; Bluetooth can make up for the shortcomings of NFC communication distance, and is suitable for long-distance data communication. Therefore, NFC and Bluetooth complement each other and exist together. In fact, the fast and light NFC protocol can be used to guide the Bluetooth pairing process between two devices and promote the use of Bluetooth.
So how does the NFC work?
NFC is a wireless connection technology that provides easy, safe, and rapid communication. Its transmission range is smaller than RFID. RFID transmission range can reach several meters or even dozens of meters, but because NFC has adopted a unique signal attenuation technology, Compared with RFID, NFC has the characteristics of close distance, high bandwidth, and low energy consumption.
Second, NFC is compatible with existing contactless smart card technologies and has now become a formal standard supported by more and more major vendors.
Thirdly, NFC is also a close connection protocol that provides easy, secure, rapid and automatic communication between various devices.
Compared with other modes of connection in the wireless world, NFC is a close-range private communication method.
Finally, RFID is more used in production, logistics, tracking, and asset management, while NFC plays a huge role in access control, public transportation, and mobile phone payment.
The newly emerging NFC mobile phone has a built-in NFC chip that forms part of the RFID module and can be used as an RFID passive label -- to pay for the cost; 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 mobile information access. Through the NFC phone, people can connect with their desired entertainment services and transactions anywhere, anytime, through any device, to complete payments, obtain poster information, and so on.
NFC devices can be used as contactless smart cards, smart card reader terminals, and device-to-device data transmission links. Their applications can be divided into the following four basic types:
For payment and purchase of tickets, for electronic tickets, for intelligent media, and for the exchange and transmission of data.
