The difference between NFC and RFID 2019-05-24

What is the difference between NFC and RFID?




rfid 

NFC technology originated from RFID, but there are certain differences compared with RFID,

 Including the following:

1.Working frequency

NFC operates at 13.56 MHz, while RFID operates at low frequencies, high frequencies (13.56 MHz) and ultra high frequencies.

2.Working distance

The working distance of NFC is theoretically 0~20cm, but in the realization of the product, due to the special power suppression technology, the working distance is only 0~10cm, which ensures the safety of the business. Since RFID has different frequencies, its working distance ranges from a few centimeters to tens of meters.

3. Working mode

NFC supports both read and write modes and card mode. In RFID, the card reader and the contactless card are two separate entities and cannot be switched.

4. Peer-to-peer communication

NFC supports P2P mode, and RFID does not support P2P mode.

5. Application areas

More applications for RFID are in production, logistics, tracking and asset management, while NFC works in areas such as access control, bus cards, and mobile payment.

6. Standard agreement

The underlying communication protocol of NFC is compatible with the underlying communication standard of high frequency RFID, that is, it is compatible with the ISO14443/ISO15693 standard. NFC technology also defines relatively complete upper layer protocols such as LLCP, NDEF and RTD. In summary, although NFC and RFID technologies are different, NFC technology, especially the underlying communication technology, is fully compatible with high-frequency RFID technology. Therefore, in the field of application of high frequency RFID, NFC technology can also be used.
