Near Field Communication (NFC) was born as a specialized subset of the 13.56MHz RFID technology in 2002. Initially used for access control and public transport payment cards, the integration into credit / debit cards and smartphones is driving rapid growth not only for payment, but also as an always-on radio link for simple pairing, diagnostic readout, parameter programming and much more.
Being one of the pioneers of RFID and NFC technology, ST offers a comprehensive range of HF RFID/NFC products, covering all NFC application needs, supported by a rich ecosystem. The devices include NFC / RFID tags, Dynamic NFC tags, NFC / RFID readers & NFC controllers, including secure element for secure NFC applications and turnkey solutions.
ST is proud to be a Sponsor Member of the NFC forum.

NFC/RFID Calculators to support your design
Our NFC / RFID set of calculators can help you with your ST25 NFC (13.56MHz) or RFID (UHF) designs:
- NFC Inductance Calculator provides the inductance value of a 13.56MHz rectangular antenna based on your footprint requirements and it applies to all ST25 Tag and Reader products
- NFC Tuning Circuit Calculator provides the component values of the matching network for a given NFC antenna and it applies to ST25R Readers
- Link Budget calculator helps you assess whether a UHF RFID Reader can establish an RF link suitable for a reliable Reader /Tag communication and it applies to the ST25RU3993 Reader
