Why does it take so long? Where’s the bottleneck? Where I lived over the last years (two countries in Europe), I don’t even have to use the physical card. I just use contactless payments with the phone. Prior to that, it was contactless with card. Even ATMs work with contactless (not all, yet). Prior to that, it was chip. I honestly don’t even recall the time when the magnetic stripe was needed. (edit) Think of this:…
To play devil's advocate – who cares? We've had magnetic strips for decades and they work fine. Yes, they're insecure but anti-fraud measures taken by the bank can mitigate that. If this helps more stores accept payments without having a painful transition isn't that worth it? I use Apple Pay most places but I don't mind having to use a strip once in a while or if others do.
How painful could it possibly be to go and buy a new card reader? Why doesn't the payments provider offer them as part of the service? They are not so expensive.
