RFID radio frequency identification is a non-contact automatic identification technology. It automatically recognizes target objects and acquires relevant data through radio frequency signals. The identification work can work in various harsh environments without manual intervention. RFID technology recognizes high-speed moving objects and recognizes multiple labels at the same time, making operation quick and easy.

 

NFC technology is born out of "contactless radio frequency identification" (RFID) and interconnection technology between wireless devices. Like RFID, NFC information is also transmitted through the electromagnetic induction coupling of the radio frequency part of the spectrum, but there is still a relationship between the two. A big difference. First, NFC is a wireless connection technology that provides easy, secure, and fast communication with a smaller transmission range than RFID. Second, NFC is compatible with existing contactless smart card technology and has become the official standard supported by more and more major vendors. Again, NFC is a close-range connection protocol that provides easy, secure, fast, and automatic communication between devices. Compared to other connections in the wireless world, NFC is a close-range, private communication method.

 

NFC and RFID are both non-contact transmission methods. They have different technical characteristics and can be used for various purposes. The technology itself has no advantages and disadvantages.
