Britain to introduce compulsory digital ID for workers

I don’t understand what is wrong with this system:

“Please employ me.”

“OK, fill out this form with your name, D.O.B. and national insurance number, and if it matches against the government database then you can have the job.”

What am I missing here? I suppose they could use someone else’s details, but then HMRC should be able to easily see that the NI account seems to have multiple taxpayers.

You will also want a photo that matches the face presented every time your gig worker looks at his phone to see the next order, etc or better yet fingerprint
