Different operating frequency bands

NFC can be understood as a subset of RFID technology, which uses the 13.56MHz frequency band, while RFID also includes other frequency bands. RFID has many working frequency bands, including 125KHz in the low frequency band, 13.56MHz in the high frequency band, 433MHz and 915MHz in the ultra-high frequency band, and 2.4GHz in the microwave band.

Different communication distance

NFC is called near-field communication, and the communication distance is really very close, not more than 0.1m. There are many kinds of RFID, and the recognizable distance is also different. Like RFID access card, the recognition distance is similar to NFC. However, for ETC applications, the recognition distance is required to be long. The recognition distance of long-distance RFID can reach tens or even hundreds of meters.

Different application scenarios

Whether active or passive, RFID is mainly used to identify objects. RFID technology is widely used in logistics, transportation and warehousing to track goods. The NFC chip has a higher degree of integration, including a card reader and a label. In addition, the two-way communication capability of NFC has been strengthened. In other words, NFC can not only be identified as a tag, but also be used for data exchange as a two-way communication mode.
