RC5222 Not reading any card

Hello,

I connected my RC522 RFID reader to my Arduino (From Dragino).

*****************************
MFRC522 Digital self test
*****************************
Firmware Version: 0x91 = v1.0
-----------------------------
Only known versions supported
-----------------------------
Performing test...
-----------------------------
Result: OK

MRFC’s firmware check says results OK but no card gets detected. I tried with like 3.

Is my card reader faulty? Any way to confirm?
