NFC or Near Field Communication is a method of wireless data transfer that detects and then enables technology in close proximity to communicate without the need for an internet connection. It’s easy, fast and works automatically.
NFC tags are a type of High Frequency RFID technology. All NFC tags are HF, but not all HF RFID tags are NFC. NFC operates in a very specific subset of high-frequency range – 13.56MHz – and have very different use cases and implementation considerations from other RFID categories.
