I have tried to use Arduino Uno with RFID-RC522 module. It is good work[1] and read rfid cards. But Arduino Yun doesn't work with RFID-RC522 module.
What is diffrent Uno and Yun?

According to the link you provided, we can see that the RFID-RC522 uses SPI to communicate with Arduino.
On Arduino UNO, the SPI pins are located as follows:
On the Arduino YUN, this is different though; as stated there (bold highlight is mine):
SPI: on the ICSP header. These pins support SPI communication using the SPI library. Note that the SPI pins are not connected to any of the digital I/O pins as they are on the Uno, They are only available on the ICSP connector. This means that if you have a shield that uses SPI, but does NOT have a 6-pin ICSP connector that connects to the Yún's 6-pin ICSP header, the shield will not work.
Hence you can not wire the RFID-RC522 module the same on UNO and Yun. For the Yun, you'll have to follow this wiring picture:
Pin 1 in image above is the pin that is marked with a dot on the Yun PCB.
Also see the ISP-header layout, at the lower-right corner of the yun_by_pighi Yun pinout diagram.
I had the same issues Thanks for help .However I made the following connections then above mentioned
RC522 RFID borad Arduino YUN (as per the github example code dumpinfo) chip select (nss ) - Pin 10 Rst - Pin 9
Link for Gihub RFID RC522 Hope it helps someone who is stuck
