Introduction

The SparkFun Qwiic Dynamic NFC/RFID Tag features the ST25DV64KC dynamic Near Frequency Communication (NFC) / Radio Frequency Identification (RFID) tag IC from STMicroelectronics©. The ST25DV64KC offers 64-kBit (8-kBytes) of EEPROM memory which can be accessed over both I2C and RF (NFC)! It's a state-of-the-art tag which conforms to ISO/IEC 15693 or NFC Forum Type 5 recommendations. You can read and write the tag's memory using NFC even while the tag is powered down or disconnected!
