B4CKSP4CE ACS NFC/EMV/RFID reader based on ESP32(S2), PN532 and RDM6300

Allows to:

• Read UIDs from NFC tags
• Read PANs from EMVCo cards (including VISA, MasterCard, MIR)
• Read UIDs from RFID tags (deperecated and not used for now)

To build the project you also require to create src/secrets.h with defines for:

#define SECRET_WIFI_PASSWORD "wifipassword" // wifi password
#define SECRET_OTA_PASSWORD "otapassword" // ota update password

Also probably you need to change the WIFI_SSID and OTA_HOSTNAME defines in src/mcu_config.h for your specific environment.
