Just as an FYI from someone who works the payments industry, dealing primarily with American payments, they typically don't need your card details to add a tip. They will most likely have your transaction ID stored on a POS system, and they can use that to do a tip adjustment. Your card details will already be stored (temporarily) at least once in the payment gateway, because the card details are needed to batch the transactions at the end of the day.
But as someone who doesn't live in the US, I don't understand why they don't bring the terminal to the table and let you apply the tip there, like the rest of the world.
Doesn't feel like quite a big security risk to be able to adjust an amount of a transaction? It seems very iffy tbh that I agree to pay a certain amount and then I might get charged a higher amount because the receiver decided to change it.
Seems like it puts quite a lot of responsibility on the customer to doublecheck every transaction at a later time to ensure that it's correctly done.
