The Design And Implement Of The NFC Multiple Protocol Reader And Writer

NFC(Near Field Communication) is a new type wireless communication technology and Compatible with the exiting13.56MHz RFID technology. It covers the shortage of the traditional close-range wireless communication technology in the respect of safety performance and connection speed. There are broad prospects for combining the NFC technology with MID(Mobile Internet Device).The design of the NFC multiple protocol reader and writer is based on putting to use the NXP PN532NFC chip combined with the Arduino Mega2560. The important feature of the device is support for multiple protocols.The begin of the paper is about the NFC protocols and the operating principle. And then the standard for design. At last the design of the hardware and the software test system. The hardware includes the antenna circuit with the EMC circuit and the matching circuit. Put to use the NXP PN532acts the NFC chip combined with the Arduino Mega2560. The hardware system is demonstrated by the software test system. The conclusion shows the device could act the reader and writer of the ISO/IEC14443Type A PICC, ISO/IEC14443Type B PICC, Felica PICC, NFCIP-1NFC mode at13.56MHz.
