QR codes, NFC, Bluetooth, and RFID are distinct wireless technologies with unique applications. NFC (Near Field Communication) stands out for secure, short-range interactions like payments and access control. Here’s a detailed comparison and a breakdown of how NFC operates.
| Feature | QR Codes | NFC | Bluetooth | RFID |
|---|---|---|---|---|
| Range | Visual line-of-sight (0–5 m) | 0–10 cm | 10–100 m | 1 cm–100 m (passive/active tags) |
| Data Transfer | Static data (URLs, text) | Two-way dynamic data exchange | High-bandwidth (audio, files) | One-way ID/tracking |
| Power Source | None (printed) | Powered by reader (passive) | Requires battery (BLE/Classic) | Passive (reader-powered) or active (battery) |
| Security | Low (easily copied) | High (encryption, short range) | Medium (pairing required) | Varies (HF/UHF standards) |
| Use Cases | Marketing, menus | Payments, access control | Wireless headphones, IoT sensors | Inventory tracking, toll systems |
