ST25T product family offers NFC/RFID ICs for contactless applications. They include short and long range (ISO/IEC 14443A/B & 15693) and feature EEPROM memory (from 512-bit to 64-Kbit).
What is an ST25 NFC tag?
A near field communication (NFC) tag consists of a tag IC chip and an antenna. ST manufactures ST25 NFC tag ICs for tag makers, who connect the IC to an antenna to build operational ST25 NFC tags.
These NFC tags do not require batteries to communicate with NFC readers like smartphones. They harvest the power they need directly from the magnetic field of the reader positioned in close proximity to the tag.
The ST25 NFC tag and the reader exchange data using specific NFC instructions defined by standards for contactless communication.
Any physical object with an ST25 NFC tag can therefore offer an advanced digital experience to the consumer.
ST25 NFC tags can enhance user experience in several ways, depending on the targeted application. For instance, you can engage with consumers, authenticate goods, and even validate your bus ticket.

ST manufactured NFC ICs meet all the requirements for effective NFC applications. The "T" in ST25T product names denote tag products in the ST25 family.
