This is the brief, bright chime heard when an iPhone payment goes through, a single clean tone that marks a purchase as complete in about a second. It gives a small, satisfying jolt of relief, the feeling of money landing exactly where it should. It comes from the payment confirmation on an iPhone, the sound people recognise from tapping to pay in a shop.
