It doesn't make any difference if there's a card in front of the reader or not, I still get status 2, backbits 11 or 61016.

I've tried two different boards, so unless the crystal is broken on both, I expect that's not the problem. I'm willing to test but I don't have voltmeter or oscilloscope.

I'm willing to buy different hardware if you have any suggestions.

 I don't know what to say now, if you have time (LOOOONG) wait it arrive this board to me too I can do some inspection at my side, I bought few day ago and at almost 20 to 40 day can elapse before delivery... I hope we can solve trouble I bought 5 board to make some access control as teaching exercise.

 Another hardware I don't know for now, this is most cheap and popular, I know TI device but it was expensive and more complex to use.

 If you are on Europe try olimex but it is much more expensive

 on USA try sparkfun adafruit pololu or similar.

IMHO is better solve issue before to change hardware, both board answer at same deterministic mode?
