IBM card readers tend to be more demanding, since they
(at least the
ones I know) push the card into the reader by its far edge. This is
done with a chunk of metal that has a step on it whose height matches
the card thickness.
IBM's card readers varied greatly in quality - the 2501 would suck up
anything, and the 2560 MFCM was known as the "Mother Fucking Card
Mangler".
