NFC Arduino Shield

NFC Shield is a Near Field Communication interface for Arduino build around the popular NXP PN532 integrated circuit. NFC 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 platform technology standardized in ECMA-340 and ISO/IEC 18092. NFC technology is regulated by Near Field Communication Forum which standardizes NFC communication between devices -- how they pair, share data and allow a secure transaction to happen.NFC Forum develops and certifies device compliance with NFC standards . NFC communication range is up to 10 mm. But, this is limited by the antenna and power radiation design. Most devices work within a range of 10mm. NFC Shield antenna is designed to work within a range of 10mm. NFC Shield provides all necessary circuitry for PN532 like 27.12Mhz crystal, power supply. It also breaks-out the I/O pins of PN532 for easy access. The communication between Arduino and NFC Shield is via SPI.

• Arduino Shield compatible. No soldering required.
• SPI interface. Hence, most Arduino pins are available for other applications.
• Built in PCB Antenna.
• Supports both 3.3V and 5V operation using TI's TXB0104 level translator.
• Socket to connect other shields.

Applications

• Use as a RFID reader with Mifare One tags (ISO14443 Type-A).
• Build visiting card sharing system.
• Build attendance systems.
• Design authentication systems.
• Read Smart Posters.
• Securely exchange small data with other NFC devices
• Use with Seeeduino ADK Main Board for creating mobile NFC applications.
• And other endless possibility.
