Britain to introduce compulsory digital ID for workers

>The proposals are the government's latest bid to tackle illegal immigration, with the new ID being a form of proof of a citizen's right to live and work in the UK.

How does a digital ID solve an illegal immigration problem? I watched the video and the suggestion is that this makes it easier for employers to verify that someone is authorized to work. Is that actually true? I don't live in the UK and have not visited in several years. If the idea is that a digital ID authorizes employment ... well I hope people can see the problem, here.

Of course a digital id doesn’t prevent illegal immigration.

Proper border checks prevent illegal immigration.

The digital ids are introduced for other reasons - this is something Tony Blair has been pushing for a long time.

My understanding is that it makes checking job eligibility easier, so enforcement of non compliance is easier.

A big source of illegal immigration is visa overstay (https://migrationobservatory.ox.ac.uk/resources/briefings/un...), which ID can solve by tracking the visa status.

There are benefits to UK citizens, such as being easier to open a bank account and to comply with Voter ID laws.
