It is popularly said that only cash is true.
But one can confidently say goodbye to this old way.
More and more people are paying more and more often by card, their cell phone or even their watch.
Cash is on the decline.
Speaking this simple truth is easy to provoke angry reactions.
Few topics become so emotional so quickly and are so little looked at in a sober way.
That doesn't have to be a problem, but it can become one, namely when people are left behind. One of the great things about cash is that it's very democratic. Anyone can own and keep it, from the homeless to the manager, from the child to the elderly. You don't need any prerequisites for this, neither an account nor a modern telephone. When stores only accept card payments, people are potentially left out, and that's a problem. But of course cash also has problems, be it the environmental balance, black money or simply the practicality.
If you want to pay by card because of this, you often face problems.
Because there are still indications in many shops that you can only pay by card above certain amounts, that credit cards will be declined, or that there is no terminal at all.
This is hostile to technology and also unfriendly to customers.
It would be easiest if you just let people pay how they want.
