NFC, short for Near Field Communication, has been increasingly ordinary and totally integrated into our life. As more and more NFC mobile phones emerge, a growing number of Arduino enthusiasts expect to learn NFC / RFID technology, therefore, in order to better serve the community and facilitate open hardware, we provided a kind of Arduino kits for quick starters, which assured hobbyists to promptly understand NFC, including development, reading and writing, uploading. Besides, the kits equipped with several interesting NFC tags, such as pretty clear tag , routine card tag, sticker tag as thin as a paper, also coins tag smaller than a silver coin, bracelet tag as well, and so on. The application of them is available for you to swiftly and conveniently bring DIY access control, ID identification , and other technology into reality.
The kits also contained the updated and improved Freaduino UNO, which enabled you to comprehend NFC at length, meanwhile, fast and expediently master Arduino.
FID / 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 operate on ISM band of 13.56 MHz Frequency. NFC communication range is up to 10 cm. 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 1cm. 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.
