What Is NFC?
NFC (Near Field Communication) is a wireless technology enabling data exchange at short ranges — typically 4 cm or less.
How It Works
- Passive NFC Devices: Draw energy from an active NFC device; no power source needed. Contactless cards and NFC tags are examples.
- Active NFC Devices: Have their own power source; can send and receive data. Smartphones and POS terminals are in this category.
NFC operates in three modes:
- Reader/Writer Mode: Reads or writes NFC tag data.
- Peer-to-Peer (P2P) Mode: Shares data between two devices.
- Card Emulation Mode: Makes a phone behave like a contactless payment card.
Role in Payment Systems
Major NFC payment platforms include:
- Apple Pay (on iOS)
- Google Pay (on Android)
- Samsung Pay (on Samsung devices)
- Banks' contactless card solutions
NFC Payments on Smartphones
- Fast and Easy: Bring the device close to a POS for instant payment.
- Security: Tokenization technology protects card information.
- Multiple Card Support: Store multiple cards in one digital wallet.
- Wide Application: Used everywhere from supermarkets to public transport.
