RFID-RD522 with Python

Question

Good morning guys!!

I’m trying to connect a module RFID with PYHTON in the Raspberry B

I followed the following tutorials:

http://www.embarcados.com.br/rfid-raspberry-pi-python/

Apparently everything is ok, but when I put the system to run, simply does not work, is waiting for me to approach the card, I approach and does not give anything!

Someone’s been there and can help me?

From now on I am grateful to all...

I never programmed in python, nor had used linux (Raspbian)
