In Germany Sparda-Banken and, I think, Volks- und Raiffeisenbanken support tap-to-pay through their apps. (And maybe other banks providing apps developed by the same contractor, Atruvia AG.)
PayPal also offers tap-to-pay, though I recently had to disable Graphene's "secure app spawning" feature for the PayPal app to get it to open.
