You should check your mfrc522 chip if it's properly powered and the NRSTPD pin is correctly set. All your read requests return 0 so most likely the chip is in power-down state (or not powered at all). You can also check the soldering of your 522 chip. I have dealt with many these chips and what I remember is the tragic soldering pads on these that cause many problems during PCB soldering.
