The practical steps needed to accelerate a UK digital identity ecosystem https://buff.ly/3aZ58je
“Using open banking APIs to build a digital ID system presents a fast and low-cost route, enabling broad adoption and inclusion through its wide availability.”
This is essence correct, but we must be sure to build a system that leverages bank identities to deliver a national entitlement service, based on verifiable credentials, not a national identity service based on outdated post-war notions of digitising the identity infrastructure created in Edwardian times as a bureaucratic response the the urban anonymity of industrial revolution-era Europe.
Spoiler alert: while this would be in their best interests, the banks show no sign of getting their act together to do this, so the government (if it takes the Kalifa report seriously and wants the UK to become a more competitive financial services jurisdiction) will have to make them.
