NFC (Near Field Technology) is a short-distance radio technology that enables communication between devices that are held close together. NFC traces its roots in RFID technology and is an open standardized platform technology. It operates at 13.5 MHZ frequency and is widely used like RFID to recognize cards/tags (Mifare Cards / Tags)
It can be used as an alternative to travel card using the read/write memory provided by cards/tags. Some mobile phones comes with NFC inbuilt - they are used as readers of cards, tags, smart posters with a Web URL(like a Mobile QR-Code reader).
NFC Shield Features
- Arduino Shield compatible. No soldering required.
- Read/Write 13.5 Khz RFID
- SPI interface. Hence, most Arduino pins are available for other applications.
- Built in PCB Antenna.
- Supports both 3.3V and 5V operation.
- Socket to connect other shields.
- The maximum communication range of this NFC Shield is about 5 cm.
- Use as a RFID reader with Milfare one tags (ISO14443 Type-A) and cards (13.56Mhz).
- Build visiting card sharing system.
- Build attendance systems.
- Read Smart Posters.
- Securely exchange small data with other NFC devices
- Use with Arduino ADK for creating mobile NFC applications and many others applications
