Cash might be trickier.

I doubt cash will exist in 5 years, because we have the technology to replace it. People only use cash now when the they have to otherwise it is swipe a card or smart device.

Agreed. But that would mean that everyone would be required to carry a means of paying electronically. A credit card or a debit card can be hard to obtain for some. Especially kids or people with bad credit.

It makes sense that cash would be a thing of the past. But it isn’t clear how it would happen.
