The UK’s new digital ID card scheme, announced by Keir Starmer on September 26, has two big questions swirling around it. Is it a solution to illegal immigration? And will it give the government too much power to monitor people?

These questions are likely to dominate discussion and debate for some time. A petition has been posted and civil liberty groups and politicians are already questioning the value of the scheme. But what is the reality?

What is a digital ID card?

Similar to the NHS app and various other existing digital cards, the new scheme will create a universal form of identification stored on mobile phones. When accessing public services, the ID could be used in the same way similar schemes are used across Europe, offering the promise of a more efficient process. Estonia has famously operated a digital ID system since 2002.

One of the aspects of the new scheme that may be overlooked in the forthcoming debate is the benefits this would have in potentially reducing bureaucracy, cost, fraud and waiting times when people are trying to prove they are eligible for certain services. While there are concerns over ID cards from a civil liberties point of view, their use in improving efficiency is something to bear in mind.

The other imperative in this scheme is monitoring who has the right to work in the UK. Anyone wanting to work or rent a home in the UK would need one, replacing the current practice of using a variety of documents such as driving licences, national insurance numbers and gas bills.

There is therefore an expectation that this will affect illegal immigration by deterring people who don’t have the right to be in the UK from trying to get jobs. Employers and landlords would need to examine ID cards to confirm the identity of applicants.

Illegal immigration and the shadow economy

Combating the flow of illegal immigrants has been a consistent problem for both the current Labour government and the previous Conservative regime. The appeal of the UK is related in part to the work opportunities available to those who can make it to the country and blend in.

In principle, the current eVisas scheme and the new digital ID card would cut off access to legitimate work for those entering the country illegally – although groups such as Migrants’ Rights Network have questioned the value of the eVisas scheme for those wanting to prove their immigration status.

With the political debate focusing on trying to stop small boat crossings, this may seem like an indirect way to address a problem – but cutting off access to work could have an impact on the appeal of the UK in the first place.

Those trying to stay in the UK undetected would need to work in the shadow economy and live in accommodation that did not check ID. The shadow economy is estimated to be 10.8% of GDP in the UK. Both activities could lead to increased dependency on organised crime groups and human traffickers.

Research suggests technology has been key in reducing crime over the past 20 years. Solutions to fraud have often been focused on improving security around identification processes, such as the introduction of facial recognition technology in passports. Perhaps digital ID cards are the next hi-tech solution needed to address illegal immigration.

Stepping into the future

ID cards have been tried and proposed before with similar intentions, so this is not a radical new idea. Also, we all carry a collection of digital ID on our phones, so in many respects, people are not being asked to do something we do not already do.

What could capture the public’s attention and concern, however, is the idea that the card is mandatory and universal. If it is only used in the specified circumstances of accessing public services, seeking employment or rented accommodation, then there is no need to see the scheme as anything more than a new way to be efficient.

But will the demand to produce the card outside of these situations become a common practice in efforts to seek out illegal immigrants? What happens to those who do not have access to their digital ID card, or do not want one? Will it create a rift in society by providing more protection from illegal immigration?

These questions are certain to be raised as the government moves ahead with its plan.
