Adafruit ST25DV16K I2C RFID EEPROM Breakout

Adafruit ST25DV16K I²C RFID EEPROM Breakout is a unique RFID tag that works with mobile phones and is reprogrammable over I²C. This RFID is based on ISO/IEC 15693 (13.56MHz) contactless interface standard that is helpful when a tag is re-written dynamically when connected to a controller. The ST25DV16K can also be used as I²C to RFID transfer system to wirelessly send and receive data from mobile devices. The breakout provides an ST25DV04 chip that supports circuitry and a PCB trace antenna for easy connections.
