NFC

Definition

Near Field Communication, the 13.56 MHz contactless radio interface used for tap-to-pay. Built on ISO/IEC 14443 and underlies UPI Lite and RuPay contactless.

Frequency
13.56 MHz
Standard
ISO/IEC 14443
Use case
Tap-to-pay contactless card and device transactions
Range
Contact or a few centimetres only

Common questions

Why does NFC matter in card fraud examinations?+

Contactless transactions leave a different forensic trail than chip-and-PIN or magnetic-stripe use, since no PIN entry or signature is captured, so examiners rely on terminal logs, timestamps and proximity to establish who initiated a tap payment.

Can NFC data be skimmed the way magnetic-stripe data is?+

Relaying and eavesdropping attacks exist because NFC has no line-of-sight requirement, but the underlying ISO/IEC 14443 protocol uses cryptographic authentication that makes simple stripe-style cloning far harder than with legacy magnetic cards.

How does NFC relate to UPI Lite and RuPay contactless?+

Both schemes ride on the same 13.56 MHz NFC radio interface for tap transactions, so the physical and radio-layer evidence an examiner recovers from a terminal or device is common across these payment systems even though the backend rails differ.
