Outline the difference between NFC and RFID

Author:admin   AddTime:2021-08-25

First, NFC integrates contactless card readers, contactless cards and point-to-point functions into a single chip, while rfid must be composed of readers and tags. RFID can only read and determine information, while NFC technology emphasizes information interaction. In layman's terms, NFC is an evolved version of RFID, and both parties can exchange information at close range. The NFC mobile phone has a built-in NFC chip, which forms part of the RFID module. It can be used as an RFID passive tag for payment; it can also be used as an RFID reader for data exchange and collection, and it can also communicate data between NFC mobile phones. .



Second, the transmission range of NFC 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, compared with RFID, NFC has short distances, high bandwidth, and low energy consumption. Features.

Third, the application direction is different. NFC is more aimed at communicating with consumer electronic devices, while active RFID is better at long-distance identification.

With the popularization of the Internet, the mobile phone, as a direct intelligent terminal of the Internet, will surely cause a technological revolution. Just like the previous standard configurations of Bluetooth, USB, GPS, etc., NFC will become an important standard for mobile phones in the future. Through NFC technology, Mobile payment, watching movies, and taking the subway can all be realized, and will play a greater role in our daily lives
