I can't think of a single retailer in the UK that takes card payments, but doesn't support contactless (including Google Pay and Apple Pay).

Ignoring very small shops that don't take cards at all.

Really? Even in England everything is just tap. I have an Android phone, so my flow is "take phone out of pocket -> tap" (because it's already unlocked by fingerprint by the time it comes out). That's basically the same as with the wallet, I just don't carry the wallet.
