Tools & Software

An NFC reader is able to setup and sustain communications with a tag or a NFC controller in all NFC modes. The ST25R NFC readers provide multiprotocol support for 13.56 MHz communications such as ISO 14443 Type A or B, ISO 15693, ISO 18092, FeliCa and NFC Forum protocols. Our NFC reader ICs and chips integrate an SPI interface to communicate with a host microcontroller.

As a main provider of Near-Field Communication technology, ST's complete NFC reader portfolio will help you design and develop the most effective and secure contactless solutions for all embedded, payment and automotive applications.
