How many times can I pay for purchases in a physical store without taking my phone out of airplane (offline) mode?

Question

Information Security

It would be logical if the application, having access to the Internet, would make a certain stock of "charges", that is, one-time access codes or card numbers, which would then be used for purchases.
After all, if the signal is always the same, then a hacked reader can remember it and transmit it where it should not. And then it is difficult to find the culprit if there was more than one reader in the entire history.
