Copenhagen (well, Denmark) has two NFC card (Rejsekort) readers at the front of every bus, with more at other doors on busier routes (ending A or C). People with commuter passes can vaguely wave them towards the driver as they board, or generally not bother.
If you want to be infuriated by how slow things can be, try a bus in Malmö.
Malmö (I assume Skåne) has a 2D-barcode-based system, where everyone has to validate their ticket on the barcode reader when they board a bus. This is about as reliable as you'd expect, including the usual fiddling with brightness settings etc. They used to have an NFC card system, but for some reason discontinued it.
[But I think the GP meant a system with ticket barriers on the metro/trains, like London, Paris, Rome and Madrid.]

As an occasional visitor with a day pass, the experience is just the driver yelling at me, and me having to take my gloves out, get the thing and show it to the driver.

Because app is cheaper and they can gather data to sell it or just their own tracking.
Last time I was in malmö, I remember being on a large square trying to get a bus to go to our hotel. And there were like 15 different lanes named with unsorted letters, and by the time we'd found the lane we'd miss the bus. Repeat this like 4 times.
