Not strictly true.
If you have a card long enough (several years between issue and expiry, say) and you use it often enough, the magnetic strip can start to fade and transactions can fail. More and more often. Edit: It might have been a chip problem rather than a magnetic strip problem. I can’t remember now, but it makes no real difference to the story.
And sometimes there might be weeks with no trouble and then you’ll get that one card reader that’s particularly finicky and there’s a cold sweat moment as you realise you don’t have enough cash. “Try it again. It’s done this before.” Please work. Pleeease.
This usually happened to me in the supermarket, so that scene from InnerSpace was playing on loop in my head.
After the third or fourth time, I called the bank and they sent me a new one ASAP.




This was a long time ago. I think the replacement card I got was the first I got that had a chip in it.
Or I’m misremembering and it was the chip on the card that was acting strangely. Either way, the card was basically worn out.
