Frequently asked questions

What is the difference between NFC and Bluetooth?

NFC works only over a few centimetres and is designed for a quick exchange of a small amount of data, such as a payment or an ID. Bluetooth works over several metres and keeps a longer-lived connection for things like headphones or a keyboard. The very short range of NFC is deliberate, because it means a device must be deliberately presented to a reader.

Is NFC the same as RFID?

NFC is built on the same underlying idea as RFID, in which a reader powers and reads a nearby tag by radio. NFC is a narrower set of standards that works at very short range and allows both devices to act as reader or tag, which is what makes phone payments possible.

Does NFC need a battery in the tag?

Not usually. A passive NFC tag or card has no battery of its own; it draws the tiny amount of power it needs from the radio field produced by the reader.

What is the meaning of NFC?

"NFC" (noun) means a short-range wireless technology that lets two devices exchange a small amount of data when they are touching or held within a few centimetres of each other, used for things like tap-to-pay cards, travel passes and electronic door keys.
