Yes.
An example is the canteen at my workplace. From April this year they will no longer be accepting cash. Only card payments, contactless, tap and go, and the like. Although I did hear that at one office, where this system is already in place, the technology froze one dinner time, and it was complete chaos. All the dinners had been prepared, but no-one could pay for them. In the end, staff did pay cash, and a number of IOU notes were written by the canteen manager because no change could be given.
I find it a bit sad to be honest, because I feel we are being forced down a road we don't necessarily want to go down. How the office collections will be done in future, I really don't know. If a machine is used, you'll have to state exactly how much you want to give, rather than discreetly placing a few coins in a tin. That could be embarrassing.
