@EASAsouthwest Your customer would be right. This happens all the time with cards that are used with mobile wallets, and is a security feature that the international banking industry set up years ago. When a mobile wallet (Apple, Google) is used to pay, the verification process spits out a random 4-digit code that only Square and your customer's bank know. It is a one-time burner code that protects your customers' actual card number, or at least makes it harder for bad actors to compromise. That is just one place where this happens.
If you customer has an Apple Card, like I do, then Apple also uses this burner code system when Apple Cards are dipped or tapped.
I'm surprised your customer hasn't seen this before. It has been the banking standard for many years, now. Anyway, that's the explanation. It is not an error at all.
