That's not an issue in most of the world; I don't think any of my current cards have ever been swiped. However there are still plenty of transit tickets that use a magstripe, and having those wiped is super inconvenient.
Hotel keys are what comes to mind as the only cards that I still swipe. A year ago I checked into a hotel and went back out to the car to grab my stuff - when getting back in I learned that I had immediately wiped the magstrip by putting it in my phone pocket. Had to reroute right back to the front desk.
I was in vacation in greece and we had issues because seemingly the phones reset their magnetic keys, so we needed a new one daily until we were told to keep them in a different pocket.
I lost the ability to use a parking exit card (mag swipe) due to a having a magnet in my wallet a year ago.
All the magstripes on my credit cards, library card, etc survived magstripes for over 2 years now. Tho I guess I wouldn't know if a card got wiped recently since I've been using contactless+biometric payments for almost the same length of time in the US. I've had paper magstripes (Paris metro tickets) wiped by magsafe so it's technically possible if the magstripe is extremely cheap/weak. IIRC metros are phasing out paper tickets for this reason
Are they still used? None of my cards have one.
All the UK payment cards I've ever had have one. I don't know if ATMs use them or the chips. For payment itself contactless is now the norm.
UK printed train tickets are all magstripe. There are phone-based alternatives and contactless payment card alternatives in London. But the magstripe tickets are still mainstream.
Also UK. All of my renewed ones lack magstripes, I didn’t realise they’re still around.
