ST25R300-AQET

ST25R300-AQET is a NFC reader for payment, consumer and industrial applications. It is a high-performance NFC universal device supporting NFC initiator, NFC target, NFC reader, and NFC card emulation modes. It enables fast EMVCo® certification cycles, even under challenging conditions, with the antenna behind noisy LCD displays. The device features high radio frequency (RF) power with dynamic power output to directly drive antennas at high efficiency. It achieves large interaction distances even with small antenna sizes in access control and EMVCo® readers. It is suitable for a wide range of applications like EMVCo® PCD 3.2a compliant contactless payment terminal, access control, NFC Forum-compliant NFC universal device, WPC Qi out-of-band (OOB) communication and card protection NFC reader, NFC wireless charging (WLC) poller, WPC Ki power transmitter (PTx) communications unit, ISO/IEC 14443 and ISO15693 compliant general purpose NFC device, FeliCa™ reader/writer.
