> in general you don’t put in your PIN every time with contactless

As an American, I never get prompted in Europe for a PIN. Even for large transactions. That matches a swipe's convenience.

I believe this is controlled by your issuer. So your card issuer probably don't require PIN after n amount of swipes.

It is arbitrary and random. Some machines will ask for it and others won’t. Some automated machines will refuse US cards altogether. Wait til you’re at a tollbooth entering the Autoroute trying to use all your US cards, and none of them are accepted.

Even Visa/MasterCard?
