FAQs For NFC

What is NFC tag?
An NFC tag is a small integrated circuit consisting of a copper coil and some amount of storage. Data can be read or written to this tag only when another NFC device is brought near it because it doesn’t have a power source. The proximity of the NFC device induces power in the tag and enables data transmission.
What is an NFC Reader？
Any powered device that has its own NFC coil (like a smartphone or tablet) can act as an NFC reader. The reader device uses its battery to generate an electromagnetic field, which powers any tag brought near it. Another common example of a reader is a payment terminal, which uses NFC to authenticate a debit or credit card.
