Card acceptance is widespread with chip & pin as well as contactless working flawlessly.

ATMs
You should have no issues withdrawing cash from most ATMs with very few charging any fees at all!

All Monzo cards have some payment and withdrawal limits. To check yours before you leave, tap on the manage card icon and then tap on Spending and card limits.
