![]() ![]() NFC Shield provides all necessary circuitry for PN532 like 27.12Mhz crystal, power supply.It also beaks-out the I/O pins of PN532 for easy access. NFC Shield antenna is designed to work within a range of 1cm. Most devices work within a range of 10mm. But, this is limited by the antenna and power radiation design. NFC operate on unlicensed ISM(Industry Scientific Medical) band of 13.56 MHz Frequency. ![]() NFC Forum develops and certifies devices compliant with NFC standards. Like many other standards, NFC technology is regulated by Near Field Communication Forum which standardizes NFC communication - how they devices pair, share data and allow a secure transaction to happen. This technology is also being applied for smart cashless purchases. Few 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 can be used as an alternative to travel card using the read/write memory provided by cards/tags. NFC is widely used like RFID to recognize cards/tags (NXP Mifare Cards / Tags). NFC traces its roots in RFID technology and is an open platform technology standardized in ECMA-340 and ISO/IEC 18092. NFC is a short-distance radio technology that enables communication between devices that are held close together. NFC Shield is a Near Field Communication interface for Arduino build around the popular NXP PN532 integrated circuit. ![]()
