I lived in the US then moved to Ontario. I find that about 70% of card readers here have "NO TAP" taped across the top. Since the insert chip, enter code, wait, and approve process actually takes longer than the swipe-and-sign in the US, I've found the time spent, averaged over my actually purchases, to be about the same. It probably has more potential to improve in the future.

Back in Sweden, Chip-and-PIN was so efficient - you can insert your card, enter your pin, and get an authorization all meanwhile the cashier is ringing up your goods. Then when the total is done, you just hit "OK" on the final amount and in seconds you're done.

In pretty much every other country I've visited, you have to do the whole process serially after the total is done, which is quite slow.

Yea, frustrating that in Canada you can't enter your pin or anything until everything is rung up.

I tap everywhere in Mtl. It's rare for me to find terminals where I can't tap.

Some US establishments seem to have stopped requiring a signature under a certain dollar amount but the tap capability isn't universal and I've noticed that it even varies across locations. So either they're pilot testing or some other factor like franchise vs. corporate are at play.

The tap to pay has actually become less common, in my experience. At one point, two of my cards supported it. Now, none of them do. Le sigh.
