It's starting to go that way. I work in event food service. For a long time, our university clients in the US didn't want alcohol sales. Now, that's starting to shift but we are required to use ID scanners. They do some verification that catches bad fakes and underage IDs, but they also store logs of every scan. Later, if there's an incident, the university can ask us to dump the logs and we can tell from them when and where a specific person purchased alcohol anywhere on campus.
It isn't storing a complete, usable image of the ID, however. Just the data encoded in the barcode.
Valve also clarified today that it was the processors, not the card management companies, that they talked to. The processors were pointing at MasterCard's rules, but refusing to provide Valve with someone at MasterCard to talk to.
