It may be a temporary hardware issue.
But in this case you should not have "apparently every time we restart
the cards the time-to-failure gets shorter"
Do you have numbers about the "gets shorter"? It is 10%, 50% or 90% shorter?

Do you have the problem with different readers from different manufacturers?
