They’re not worth anything, never were but even less through the years with inflation.
If a store wants to sell something for 99 cent, they can either just take 1€ or 95 cent.
Maybe even 5 cent pieces? But that would be a bit radical.
I am a bit annoyed that easy ideas like this are never discussed in politics, or wherever. It would make our lives just a little bit easier, and having them achieves NOTHING.
That sounds a bit harsh. Me and a couple of other people I know have used contactless payments even for quite some time before COVID. It was relatively simple to set up by linking your PayPal account to Google Pay if you had an Android phone. But I agree that contactless payments weren’t widely adopted by the general German population until 2020.
