Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity. The NFC RFID module is built on the NXP PN532 standards.

Specification:

• Support NFC RFID reading and writing, P2P communication with peers
• Support I2C, SPI and HSU (High Speed UART), easy to change among these modes
• On-board level shifter, standard 5V TTL for I2C and UART, 3.3V TTL SPI
• Arduino Raspberry Pi compatible, Small Size and easy to embed into your project
• RFID reader/writer supports: Mifare 1k, 4k, Ultralight, and DesFire cards, ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX), Innovision Jewel cards such as IRT5001 card, FeliCa cards such as RCS_860 and RCS_854
