What is NFC?

Near Field Communication is a short-range wireless technology that enables secure data exchange between devices within 10cm proximity.

How NFC Works

NFC operates on electromagnetic induction principles:

1. Initiation: An NFC reader generates an electromagnetic field
2. Detection: Nearby NFC tags or devices detect the field
3. Communication: Data is exchanged using ISO/IEC 14443 standards
4. Completion: Connection closes once devices move apart

NFC Technology Stack

• Frequency: 13.56 MHz
• Standards: ISO/IEC 14443, ISO/IEC 18092
• Modes: Reader/Writer, Peer-to-Peer, Card Emulation
• Range: Up to 10cm

Use Cases

• Mobile payments
• Access control
• Data sharing
• Smart posters
• Authentication
