FNB in South Africa has a learning quick select feature for withdrawals like the one you describe. After I withdrew the same amount a couple of times it appeared on the main screen as a quick select option.

Same with language. I'm sure I was asked at some point what my language preference was, but since then I've never had to tell an FNB ATM my language choice. I still do for other banks, but that's probably because language preference isn't amongst the pieces of data which banks share between each other.

So it can be done. You don't need local storage on the ATM itself, just a few additional attributes requested and sent down when the ATM retrieves the customer account data from whichever central servers it's using.
