A lot of people assume this, but with contactless EMV there is a whole transaction flow between the card and the reader going on.

You know those 4 lights on a contactless card reader? They indicate different transaction stages between the card and the terminal. I don’t find them that useful because it’s so fast they all appear to light at the same time, but that’s what they are!
