The ST25TV device is an NFC/RFID tag IC with a tamper proof feature, and specific modes to protect customer privacy.

It features a digital signature generated by TruST25™ (a set of software and procedures), used to prove the origin of the chip in cloning detection. It embeds a configurable EEPROM with 60-year data retention, and can be operated from a 13.56 MHz long range RFID reader or an NFC phone.

The contactless interface is compatible with the ISO/IEC 15693 standard and NFC Forum Type 5 tag.
