Issues 13.56Mhz RFID module

The wiki for this rfid
doesn't work

Also it seems like we have a different version of this rfid because our rfid reads
880-v2 ROHS on top and there's a slight difference in the way the pcb is set up.

I've seen more people with this problem.
Can anyone help? We're really in need because within a week it has to work.
