I notice that "carte bancaire" was used here, not "carte bleue" and carte bleue wasn't given as an acceptable answer. Is it falling out of use in France ?

My understanding is the difference between a "bank card" (carte bancaire) and a "debit card" (carte bleue)

Presumably "carte bancaire" is the most general term which includes credit and cash cards.
