Even if you seem very nice, the waiter at this Japanese restaurant will check that you are not a fraudster. 👀 Don’t take it personally, he does it for everyone.
To do so, he will use his payment terminal. For example, he will check that the PIN code you have just entered is the PIN code for the payment card.
He can also compare your payment card with all the cards that have been used on the terminal network it is part of. In general, these are large networks, with tens of thousands of terminals. So if your card has already been used fraudulently with one of them, your transaction will be rejected immediately.
After having made these few checks, the transaction authorization request may be sent to your finance management solution. That’s us. 🙂
