"I fear that this is the thin of the wedge with regard to the demise of cash altogether."
Whilst the banks, HMRC and others with some self interest keep predicting the demise of cash, it hasn't happened and it won't happen. If the government of the day decides to stop printing notes and minting coins, people will simply use other currencies for cash transactions - they might even invent their own currencies or swap commodities.
My cash works when my phone is lost, stolen, has a flat battery or is otherwise incapacitated.
When I buy stuff for cash, HMRC, the banks and "their selected marketing partners" have no idea what I have bought.
Bank payment systems have to be paid for, which is why some traders offer a discount for cash.
