The article I was reading a few days ago seems to have disappeared. Strange.
But this is interesting:
<strong>One of the controversies of the UK design is that NHSX has chosen not to use a template provided by Apple and Google which stores most of its data on individual phone handsets, rather than a single database. While Germany and Italy have decided to adopt this template, both Britain and France favour a more centralised system — separate to the Apple and Google model — which gather anonymised “identifiers” for each app user together on a government server.</strong>
I mean, why not use a system that is already there?
