NFC — tap to open
NFC stands for Near Field Communication. A tiny chip sits inside a sticker or sign. When a phone is held close to it, the phone reads the chip and opens whatever link is stored on it. No app, no typing, no battery in the chip — the phone itself powers it for the split second it is read.
- ◆Works by holding the phone within a few centimetres
- ◆The chip has no battery and never wears out
- ◆Same technology used for tapping your card at a checkout
