damaged cards

It's not cycling that messes up bankcards, it's buying bikes. I blame the banks.

First of all its most probably the Governments fault, failing that it could be down to a cloaked alien ship presence in the area you pass through that is giving out massive radiation, failing that it could be that in fact your very poor and you dont have any money, lastly are you sure they are bank cards and not a library pass and a blockbuster card.
If none of the above most common reasons then you have a real weird problem and better call the bank.
