Just a heads-up from Denmark: card payments went completely down last night, and it wasn’t just a local glitch. Stores all over the country were affected—POS terminals dead, ATMs offline, even online transactions failed in some cases.
The payment provider Nets has confirmed the outage, but says they still don’t know what caused it. According to their statement, there’s no sign of terrorism or foreign interference—just a mysterious, wide-scale failure in the core infrastructure.
Zettle also reported a "major outage" for card processing in Denmark around the same time. Everything was back online within before midnight, but the incident left a lot of people (and businesses) stranded, unable to pay or be paid.
This is one of the most cashless countries in the world, and it really showed how brittle the system can be. No clear cause. No clear prevention. Just… silence and fallback to cash (for those who had any).
