 # X-NUCLEO-NFC09A1
 
 The code has been designed for ST X-NUCLEO-NFC09A1 expansion board to show how to detect, read and write NFC tags.
-The X-NUCLEO-NFC09A1 NFC card reader expansion board is based on the ST25R200 device. The ST25R200 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/B and ISO/IEC 15693 RF communication protocols as well as the detection, reading and writing of NFC Forum type 1, 2, 4, and 5 tags.
