this is an "OOPS" almost as big as when your company spends two hours thinking of a hashtag that nobody will ever use.
I don't know if you've ever used one but the Swiss ticket machines are nowhere near antiquated. They are all touch screen devices that support contactless payements as well as all the usual payment options and then some (reka cheques?), and offer a (relatively) good UI in at least 4 different languages.
I'd add that the rest of their IT-enabled infrastructure is really good - apps that let you buy electronic tickets for all major mobile plaforms, RFID-enabled travel passes, and up-to-the minute train live tracking.
Compared to every other country I've travelled to they are really advanced. Granted, I've not been to Japan or Singapore, but I've otherwise travelled quite a lot.

Most bitcoin vending machines have a variety of poor user experiences let alone the offered prices and limits. So far all I know about this one is the limit is low.
Regarding the UI - despite not looking "high-tech" (no animations at all -not even transitions- simple basic color scheme), I find it very good: I live in a remote village, and grandmas here have no problems using the ticket machine, even for unusual trips.
Of course they usually pay with coins, and that part takes ages ;)
