After many years of trips to Russia, this year I've noticed that almost everyone is saying платить по карте, although I do not remember almost ever hearing it before. In the past I recall hearing almost always some variant of the instrumental case: заплатить картой, заплатить карточкой, заплатить кредитной картой... Is 'по карте' a new thing? Any reflections on this development?
