You can pay with cash at Coop. Most if not all cash registers allow cash payments. Most customers don't pay with cash.
How does the cashier open the safety box to reach the money?
Or open the cash registry?
I don't even think it is legal to accept money without a working cash registry for tax registration reasons.
* I'd wager that if you know the prices and keep track of what you sell, you'd be fine recording the transactions after the fact.

My understanding was that it was just payment processing that was affected, not the point of sale systems. The scanners and things probably work fine, and I think they could accept cash payments without issue. It’s just not worth it when almost no customer pays with cash.
