It doesn't surprise me that for some charges the expiration date has to be right. There's a lot of diversity in this area.

But I know that traditionally, the expiration date wasn't part of authentication. When I did it, it was in 1999 using a traditional merchant credit card terminal.

Banking computing standards often take a decade to make even a trivial change because regulators are very careful. I'm pretty sure that this terminal wasn't even capable of transmitting the expiration date I typed to its partner.
