The X-NUCLEO-NFC06A1 NFC card reader expansion board is based on the ST25R3916 device. The expansion board is configured to support ISO14443A/B, ISO15693, FeliCa™ and AP2P communication. The ST25R3916 manages frame coding and decoding in reader mode for standard applications, such as NFC, proximity and vicinity HF RFID standards. It supports ISO/IEC 14443 Type A and B, ISO/IEC 15693 (single subcarrier only) and ISO/IEC 18092 communication protocols as well as the detection, reading and writing of NFC Forum Type 1, 2, 3, 4 and 5 tags. The on-board low power capacitive sensor performs ultra-low power wake-up without switching the reader field on and traditional inductive wake-up to select amplitude or phase measurement. The automatic antenna tuning (AAT) technology enables operation close to metallic parts and/or in changing environments.
