Product overview

Description

The ST25TA-E devices are NFC/RFID tag ICs with solid security and privacy features.

They hold an unique off-chip generated digital signature through TruST25 services (a set of software and procedures) used to prove the origin of the chip in cloning detection.

The ST25TA-E devices also generate on-chip digital signatures dynamically through Edge TruST25 services to prove the origin of product in cloning detection and associated datas. They embed custom certificates used for enrollment verification in cloning detection.

The Augmented NDEF is an automatic contextual NDEF messaging service that allows tags to react to dynamic content without user interaction.

The ST25TA-E devices have a configurable flash memory with 25 years of data retention and work with a 13.56 MHz RFID reader or an NFC phone.

The contactless interface is compliant with the ISO/IEC 14443 standard and NFC Forum Type 4 Tag specification.
