NFC Technology in Mobile Payments

NFC technology has revolutionized contactless payments, making transactions faster and more convenient than ever before.

What is NFC?

Near Field Communication (NFC) is a short-range wireless communication technology that enables data exchange between devices over short distances (typically 4cm or less).

How NFC Works

Basic Principles

• Magnetic Induction: Uses electromagnetic fields for communication
• Short Range: Limited to very close proximity
• Low Power: Minimal battery consumption
• High Security: Secure communication protocols

Communication Modes

• Active Mode: Both devices generate RF fields
• Passive Mode: One device generates field, other responds
• Peer-to-Peer: Direct device-to-device communication
• Card Emulation: Device acts as contactless card
