NFC (Near Field Communication, NFC), also known as the short-range wireless communication, high frequency wireless communication technology is a short-range, allowing for non-contact-point data transfer between the electronic device (within ten centimeters) to exchange data . The technology consists of a contact-free radio frequency identification (RFID) evolved, backward compatible RFID, first developed by Sony and Philips each success, mainly for mobile phones and other handheld devices to provide M2M (Machine to Machine) communication. Because of the near-field communication has a natural safety, therefore, NFC technology is considered in areas such as mobile payment has great application prospects. Meanwhile, NFC because it compared to other wireless communication technology security is better networking between schools and enterprises Chinese objects alliance as a “security dialogue” between the machines.
