The Dankort system, the almost universal card payment system in Denmark, is down this morning. It’s mindboggling to think of all the small and large disruptions this creates – paying for transportation for instance.
It’s striking that with such large systems, you get equally large disruptions. Suddenly, in a glitch, money in general is out of order. That’s huge. Enough to make you consider carrying cash around. But then again, you can’t pay for a train ticket using cash at my station.
