Alternative to laminated card?

I was asked if it was possible to laminate club membership cards. Of
course it is, but commonly available lamination pouches are longer than
a typical credit card, and won't fit in your wallet.

So, why not print on actual credit card stock? Has anyone done this?
Can it be done at a reasonable cost?

I have done a preliminary web search, but equipment I found is quite
expensive for a small club to consider.
