What is NFC?
Near Field Communication (NFC) is a set of communication protocols that enable two electronic devices, one of which is usually a portable device such as a smartphone, to establish communication by bringing them within 4 cm (1.6 in) of each other.
How does NFC work?
NFC devices can act as electronic identity documents and keycards. They are used in contactless payment systems, similar to those used in credit cards and electronic ticket smartcards and allow mobile payment to replace or supplement these systems.
Applications of NFC
- Contactless payments
- Access control
- Data transfer
- Identity verification
