Ossie, a search engine helps.
It looks a though it is being brought in on the back of Covid-19, which is convenient for the authorities, but as someone not in favour of a cashless society I am a bit concerned.
Many aspects of my life can already be tracked via phone or Internet use, though I do try to reduce that, but my purchases are my business. What I buy, where I buy it and when I buy it is my business and sod all to do with Big Brother.
Small steps using a crisis as an excuse does no sit comfortably IMO.
