MFRC522 stop working after few hours #21

Hi, And first of all, thank you for this program, that works well! I I just noticed that the reader stops readingt usually after a few hours in use, even if the program still run. Has anyone got some tips for solving this issue?

Cheers, Maxime

I had the same problem and I just found then the MFRC522.py script crashes at line 282. The line 281 initiates a loop (while i<5:) passing i to buf.append(serNum[i]) but serNum is an array of 4 elements, so try to set while i<4 at line 281.

Using spidev like in ondryaso/pi-rc522#20 solved the issue for me!
