The UK will require people eating in restaurants to identify themselves.

New Zealand's previous system, recording info about customers on paper, respected anonymity. It made the information available to collect when contact tracing needed it, but avoided creating a tracking database that the state could use for unjust purposes.

I am alarmed to read that New Zealand now requires customers to scan a QR code — with a Stalin's Dream device, evidently. That is not safe. And what about the people who don't have a portable phone?
