I've been asked by a student whether 'bank card' is a common synonym for debit card.

I started by checking wikipedia whose [article on bank cards](http://en.wikipedia.org/wiki/Bank_card) points towards it including both debit, credit and other cards. However, the [article on debit cards](http://en.wikipedia.org/wiki/Debit_card) seems to imply that bank card is indeed a synonym of debit card.

While searching EL&U, I found [an answer to the question](https://english.stackexchange.com/questions/101920/is-there-a-term-which-covers-atm-cards-credit-cards-and-debit-cards) that clearly states that, at least in Canada, bank card is a synonym for debit card.

So...
Is bank card a general synonym for debit card, or is this true only in some English-speaking countries? And if so, which countries? In the countries where this is true, which term is preferred in everyday speech?
