The adoption of contactless payments in Romania has been astonishing. When I first moved here four years ago you could only pay by card at restaurants and supermarkets and definitely not contactless. Now, four years later, you can pay contactless everywhere. Including all the little stores. Any place that supports card payments also supports contactless payments. Hell, you can hop in any bus now and buy a ticket on the spot with the contactless payment terminals in the bus. No human interaction required, you just hold up your card or phone and it prints a ticket.
Ever since Apple Pay became available, I can't remember the last time I pulled out my card.
There are only two things I still use cash for. Tipping and taxis. The latter can be worked around by using Uber or one of the local competitors.
