NFC vs QR Code — What's the Difference and Which Is Better?
NFC and QR codes both enable contactless information sharing — but they work very differently. Here's a clear explanation of which is better for which use case in Pakistan.
What Is NFC?
NFC stands for Near Field Communication. It's a short-range wireless technology that allows two devices to exchange data when they're held very close together (usually within 4cm). You use NFC every time you tap your phone to pay at a store — that's NFC. Bank cards with contactless payment also use NFC.
What Is a QR Code?
A QR code is a scannable 2D barcode that stores information visually. Unlike NFC, it requires no radio frequency. You just point your phone camera at it and your phone reads it optically. No physical proximity is needed — you can scan a QR code from across a room if it's large enough.

For Smart Tags: Why QR Wins in Pakistan
For a lost-item identification tag (like Nishaaan), QR code is clearly superior for Pakistan's conditions:
- Works with literally any phone that has a camera — including older Android phones
- No NFC reader required — NFC chips require specific hardware to read
- A printed QR code never runs out of power, never breaks electronically
- Much cheaper to produce reliably
- Scannable from a distance — useful when a tag is attached to a bag on a carousel
NFC is excellent for payment systems (JazzCash, EasyPaisa tap-to-pay) where the hardware is guaranteed. But for public-facing identification tags, QR is the practical choice. This is why Nishaaan uses QR codes rather than NFC. See our tags.
