NT3H2211W0FTTJ

The NTAG I2C plus combines a passive NFC interface with a contact I2C interface. Designed to be the perfect enabler for NFC in home-automation and consumer applications, this connected NFC tag is the fastest, least expensive way to add tap-and-go connectivity to just about any electronic device. These devices maintain full backward compatibility with first-generation NTAG I2C, while adding advanced features for password protection, full memory-access configuration from both interfaces, and an originality signature for protection against cloning.
