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

1. Contactless Payments – Tap to pay at POS machines.
2. Access Control – Office entry cards or hotel room keys.
3. Digital Visiting Cards – Tap the card on a phone to open your profile, website, or contact details.
4. Public Transport Cards – Metro or bus smart cards.
5. Event Pass / Attendance System
