image Carry cash you idiots. (Context: there's a massive blackout in Spain and Portugal that has taken down card networks, among many other things)

The claimed cause is interesting: Induced Atmospheric Vibration. Basically, if the conditions are just right, at the corona discharge threshold, the force of corona discharge leads to an oscillation with the corona discharge turning on and off. This in turn causes oscillations on overall power discharge (corona discharge can be a non-trivial amount of losses), triggering protection circuits and causing blackouts. At least, that's the one description I could find.. but it sounds plausible.
I'll never understand how someone can walk around without cash and trust their card, or even worse their phone, to always work. But the same goes for businesses not accepting cash, of course.

Hell, we used to take credit cards even when power or comms were down. Just take an imprint, the customer signs it. They get a copy, the store keeps a copy, a copy get mailed in for processing.

Some card terminals (here they are often battery powered and connected to mobile network - towers have battery/generator backup) have the option of using chip+pin offline, works great. Even with that, carry a bit of cash for emergencies, takes up little space and can save you a lot of trouble.

They stopped doing that a long time ago, new cards don't even have the raised numbers/letters (at least here), guessing it was due to the shit security.

Merchants insist using payment cards and there is already a push for "qr code payments like China", allegedly to reduce transaction cost.
