I am using rc522 for the first time with esp8266 I used some codes to read a rfid card but it doesn't work when I try it with an arduino it works just fine! I don't really know what's the problem if anyone would help me it would be great!

Problem solved by purchasing a new MRFC522. But I still don't get that if my old module works with arduino then why not ESP8266? Special thanks to @horace & @UKHeliBob for helping me and for their time.

possibly the old RC522 was a 5V version would not work with the 3.3V ESP8266
