It is not difficult to imagine a world without coins and paper money.
Cash has been in steady decline over the last 20 years. Our mobiles are morphing into our wallets, and our wallets are home to cards, not bank notes. New ways to pay are coming at pace.
The stats are well-known but worth reiterating. At the start of the millennium, 50% of transactions used cash, it is now less than 25%. Cards now account for more than half of payments. 21% of payments are made using contactless technology, it was 3% in 2015.
