As mentioned already, the pandemic has been a catalyst in speeding up the demise pf cash.
Most shops and services, apart from possibly the major supermarkets, around us, went to card only during that time.
Many have seen most of their trade continuing to be conducted by card.
Even the men's hairdressers I go to (all lady hairdressers), went card only and continued it until only this spring.
Even now they say most people prefer to use a card.
It's cut down on their tips, resulting in 2 recent price rises.
Personally, I've only used small amounts of cash twice in the last year and a half or so, paying for everything on debit or credit cards (we don't carry over any monthly debt).
Even paying for something as simple as a 4 pint bottle of milk, with a card.
As an observation, many older people have taken quite readily to contactless.
It saves them having to get to an ATM.
I queued behind several people of retirement age in the local greengrocers just the other morning.
Every single one of then used contactless.
Even my elderly mother and my mother-in-law, who are in their early 90's and late 80's respectively, mostly go cashless.
