NFC or near field communication is another form of RFID that operates at a lower frequency. This means that the read range and rates are much lower compared to the standard UHF RFID. NFC is considered passive, meaning that the NFC tag needs to be read or excited by an NFC device to receive data.
NFC technology is used for a wide range of applications like:
- Key card entry systems
- Contactless payments
- Lab animal identification
