I’m in retail management. Cash is steadily decreasing as a percentage of tender but it still requires a lot of time, expense and effort to count, store, deposit, order change, etc. Then there is the risk of loss from theft or mishandling. I doubt it will ever be totally phased out but it is rather inefficient.

The days of less and less cash use is already coming, thanks to Apple, who development of NFC-based Apple Pay has begun the even more rapid change to less cash payments.
