Etymology
The papyrus-layer word developed meanings connected with paper and writing. English first used card for a playing card, then extended it to similar small, stiff pieces carrying names, information, or messages.
In context
to a trivially counterfeitable magnetic stripe. And for very lazy criminals, we still emboss the card. So if you're a criminal in a hurry and you need to copy someone's card
