The ST25TV02KC and ST25TV512C devices are NFC/RFID tag ICs with an Augmented NDEF feature, a tamper detection interface, and specific modes to protect customer privacy.

The Augmented NDEF feature is a contextual automatic NDEF message service, allowing the tag to respond dynamic content without an explicit update of the EEPROM by the end-user.

The tamper detection interface is available on ST25TV02KC-T devices only. This interface is not available on ST25TV02KC‑A and ST25TV512C devices.

The ST25TV02KC and ST25TV512C devices hold a digital signature generated by TruST25 (a set of software and procedures) to prove the origin of the chip in cloning detection, 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 compliant with the ISO/IEC 15693 standard and NFC Forum Type 5 tag specification.
