I've never seen or heard about anyone being refused to pay with cash if they wanted to.

The only place I would pay with cash though is in a bar, all other places I prefer to pay by card.

I do agree with you there could be problems in the future where digital payments start becoming the only option (which I'm hoping for) and their certainly is a market for future products. I bet they will be looked at in the same way as VPN services are looked at now though.

Many places don't take cash, Yaki-Da[1] in Gothenburg for instance. Many (all?) restaurants on Tredje Långgatan as well, and I've also seen several places in Stockholm where they won't accept cash.

Also, many cities' communal services like busses and trains no longer deal in cash.

It seems I stand corrected.
