What Happens in the 2 Seconds After You Tap Your Card

You tap. A beep, a green tick — and somewhere behind that beep, your purchase has been turned into a token, carried through a four-player relay, interrogated by your bank, and answered, all before you've lowered your hand. And the strangest part: at that moment, no money has actually moved. This is the two-second ceremony, slowed down: what the beep really means, the number that isn't yours, the millisecond interview, why approvals are instant but refunds take days — and why the tap is the safest way you've ever paid.
