What are you referencing specifically? I work in payments and I’ve never heard of this IBM code. The card networks just use an ISO format and every front end is different (the two we have are completely different in very fundamental ways though they are definitely both old as fuck).
I assure you they won’t. It’s not going to be that expensive to only show an option if you’re in California. Companies already do this with other things like privacy related stuff.
If the company is already a scumbag company that makes it impossible to cancel, this will only stop them where they have to follow a law.
I feel like it’s pretty obvious this was a greedy and terrible idea. The fact they proposed this at all alone is enough to never trust them again. It’s not that they didn’t know. They knew. No one would be okay with this cash grab and they know it. They just didn’t realize HOW big the pushback was going to be but they DID know what they were doing was wrong.
I’m split on this. On the one hand if they didn’t have self checkout, they’d need more checkout people. On the other hand, before self checkout they didn’t really give a fuck if you had to wait in line (especially Walmart holy shit that was one of the biggest reasons I never went there, the fucking checkout line).
