Britain to introduce compulsory digital ID for workers

> Stored on mobile phones, the ID would contain details including a name, date of birth, residency status and crucially a photo - which would distinguish it from National Insurance numbers.

Surely it will be possible to also store it on some government-issued, GCHQ-vetted digital device, and not rely on foreign companies (Google/Apple) and their locked-down mobile platforms?

This is the most alarming aspect of the proposal to me. I find it wild that the government will require me, by law, to buy an expensive electronic device I don't want or otherwise need, in order to be employed. It's absolutely amazing to me that the government is forcing me to spend money in this way.

My government requires me, by law, to send it tens of thousands of dollars every year, much of it to be spent on things I don't want or need, in order to stay out of prison.

Requiring me to spend another $100 or so on a phone seems like pretty small potatoes, compared to what they intend to use the device for. I'm not saying I'd like it, but it's a detail, not the main issue.
