The end users of such cards are often not aware of the source, there's usually resellers that supply them who are always trying to save a buck here or there.

We have customers who use smartcards and we often need to read or write to them, during on-boarding they often have no clue what version or spec they are using and it often results in trial-and-error after they send us a few cards with little-to-no markings on them.
