The technical process of "pseudonymization" is explained, showing how a digital ID can prove a specific fact—such as being over 18—without revealing a user's full identity or address. By linking existing datasets from the DVLA, HMRC, and banks, the system can provide "minimum viable" information to third parties. This prevents the creation of a single, all-encompassing master database that critics fear.

The history of UK ID cards is revisited, specifically the failed mid-2000s scheme under Tony Blair and David Blunkett which was eventually scrapped by the Cameron coalition. Ocsko notes that a successful digital ID system could save 2% of the UK's GDP—approximately £44 billion—by preventing fraud. The hosts conclude that most citizens already give away more personal data to Google, Apple, and Amazon than the government is requesting for the ID system.
