I had the same issues but could not find any solution despite searching number of forums, videos and sites. Finally, I resolved the issue by these steps: 1. Make sure that you have installed the RFID library.
What kind of pin does the mfrc522 RFID reader use?
The MFRC522 rfid reader uses SPI communication protocol. Pin 13 is one of the SPi pins. So, you need to use that pin. For several hours I have been looking for a way like this, thanks, very helpful to me who just learned about arduino and rfid.
How to update the mfrc522 library on Windows 10?
Make sure that you have installed the RFID library. 2. If not installed, go to Sketch – Include library – Manage libraries – Search for RFID in the search box and install MFRC522 Library. 3. If the RFID still dont work, then go back to the same step 2 and this time you might see an option for ‘Update’.

What is the RFID library for Raspberry Pi?
There are two files that are included within our MFRC522 library that we make use of: MFRC522.py which is an implementation of the RFID RC522 interface, this library handles all the heavy lifting for talking with the RFID over the Pi’s SPI Interface.
