Stainless Steel 380mm Ntag213 Bar QR Code RFID NFC Plastic Security Seal

Q: What is NFC ? A: NFC is short for Near Field Communication,it's development technology is later than RFID. Q: What are the differences between RFID and NFC ?

Answer:

1. Working Frequency NFC is 13.56 MHz,while RFID covers low frequency,high frequency and ultra frequency.

2. Working Distance Theoretically, NFC works within 0-20 cm, yet virtually on product, a special power controlling technology made its working distance 0-10cm so as to better ensure safety operations. RFID working distance varies as it has different frequencies. 3. Working Mode NFC support read and write, card mode; RFID, reader and non-contact card are two independent entity,can not be switched.

4. Communication Mode NFC support P2P, RFID does not. 5. Protocols The underlying communication protocol of NFC is compatible with the underlying communication standard of high-frequency RFID, that is ISO14443/ISO15693 standard. 6. Application Low Frequency High Frequency ------ NFC (Non-contact IC card) RFID Ultra Frequency Micro Wave
