What is RFID, what is NFC?
RFID uses electromagnetic waves for unique identification. Every RFID chip (tag) has its own number, the UID. APPEC reads this UID and stores it as the article's identifier.
NFC is based on RFID and works in the HF frequency band (13.56 MHz). Most smartphones read these chips directly.
- LF – 125 kHz / 134.2 kHz: reader required
- HF – 13.56 MHz: readable with an NFC-enabled smartphone
- UHF – 860–960 MHz: reader required
