Wonder how they block the card, my impression was that tokenization was meant to make it harder for card chargers to be able to track a card through multiple taps like that.
- reitanuki 2y agoThey must have the card identity because you have to explicitly 'tap out' at the other end, if you don't want to be billed with a maximum fare. Don't ask me how though
