I've plugged an USB NFC/RFID reader, model ACR112U-A9 provided by ACS Ltd.
Although it is plugged I can't read anything and I keep getting this logs in console:
09/06/15 14:13:00,901 com.apple.SecurityServer[83]: reader ACS ACR122U PICC Interface: state changed 16 -> 34
09/06/15 14:13:00,902 com.apple.SecurityServer[83]: token in reader ACS ACR122U PICC Interface cannot be used (error 229)
09/06/15 14:13:01,249 com.apple.SecurityServer[83]: reader ACS ACR122U PICC Interface: state changed 32 -> 18
How can I solve this issue? Do you know what is the error 229
and why it's triggered?
