What is an NFC reader?
NFC readers communicate with smart cards, NFC tags as well as with NFC-enabled devices—such as smartphones and consumer goods. With a simple tap, they write and read data using several operating modes: card emulation, read/write, and peer-to-peer. Active NFC readers have a typical read-range of up to 10 cm and can also charge small battery-powered devices. This variety of options enables a wide range of applications and use cases.
The ST25R NFC readers provide multiprotocol support for 13.56 MHz communications such as ISO 14443 Type A and 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 applications (payment, automotive, healthcare, monitoring devices, etc.)
With their advanced features, ST25 Readers enable a wide range of opportunities. NFC Forum CR13 certified, the ST25 Readers ensure interoperability with mobile phones and all other sorts of NFC-enabled devices and cards.
The device can be used in consumer goods and industrial flow for power and data transfer to authenticate, improve safety and increase customer experience as well as to get valuable feedback on product usage.
For the best possible payment terminal experience while speeding up time-to-market, our ST25 NFC readers feature Active Wave Shaping (AWS) and Dynamic Power Output (DPO) making certification easier than before. Fully compliant with the latest EMVCo® requirements, they also integrate a Noise Suppression Receiver (NSR) to guarantee dependable connectivity in the event of noisy environments, especially when the NFC antenna is close to an LCD screen.
Low-power consumption enables access control for buildings and cars and allows a good user experience that is ensured by a large interaction volume and robustness of the solution.
