An NFC card is a contactless smart card that uses Near Field Communication (NFC) to communicate with devices like smartphones, payment machines, or NFC readers.
📡 How NFC Card Works
- NFC works through short-range wireless signals (about 4–10 cm).
- When you tap the card near an NFC reader or phone, it transfers data instantly.
- No internet or battery is required in most NFC cards.
💳 Common Uses of NFC Cards
- Contactless Payments – Tap to pay at POS machines.
- Access Control – Office entry cards or hotel room keys.
- Digital Visiting Cards – Tap the card on a phone to open your profile, website, or contact details.
- Public Transport Cards – Metro or bus smart cards.
- Event Pass / Attendance System
