This 13.56 MHz high frequency RFID reader module features a miniscule footprint, simple and intuitive API, low power consumption and excellent tag compatibility. It is well suited for medical applications, ticketing, security or safety applications. It reads and writes transponders based on ISO 14443A/B protocols. It has 4 general purpose I/O pins and supports adjustable host interfaces including USB, TTL level RS232, SPI and I2C. The ultra-low power reader/writer module supports not only the extremely popular NFC tags, but also NFC peer-to-peer and tag emulation modes as defined by ISO 18092. It allows for active data passing between NFC enabled smart phones, tablets and other devices. In addition, a micro USB port is available for direct connection to a USB host as well as an antenna output for an external antenna.
