What is an NFC reader?
An NFC reader can communicate with an NFC tags and cards (such as credit or access card, consumables) another NFC reader or an NFC-enabled device (for example, smartphone, tablet, or consumer goods) in short distance up to 10cm, and in special cases, even over longer distances.
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. NFC reader ICs 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 helps you design and develop the most effective and secure contactless solutions for all embedded, payment, and automotive applications.
Applications
With their advanced features, ST25 Readers enable a wide range of use cases. Compliant with the NFC Forum CR13 certification, the ST25 Readers ensure full interoperability with mobile phones, as well as with all other sorts of NFC-enabled devices and cards.
ST25 Readers can be used in consumer goods and industrial flows for power and data transfer to authenticate objects, improve safety, and enhance customer experience as well as to get valuable feedback on product usage.
Payment terminals equipped with an ST25 Reader can benefit from advanced features such as Active Wave Shaping (AWS) and Dynamic Power Output (DPO). These features are instrumental in achieving the latest EMVCo® certifications swiftly, thus enabling the shortest possible time-to-market. Additionally, the inclusion of Noise Suppression Receivers (NSR) ensures compatibility with noisy displays, enhancing functionality in challenging environments.
The ST25 readers are also designed to be low power, which is particularly beneficial for applications such as building and vehicle access control. Finally, their capacity to detect and operate in a comfortable range ensures the best customer experience.
