Banks have spent years verifying customer identities, yet consumers are still routinely asked to upload passports, utility bills and other documents every time they interact with a new service. A coalition of the UK’s largest banks is now seeking to change that by turning mobile banking apps into trusted digital identity gateways. If successful, the initiative could create a new layer of financial infrastructure that extends far beyond banking, simplifying digital verification across the wider economy while reducing fraud and improving privacy.
Six of the United Kingdom’s largest retail banking and financial institutions: Barclays, HSBC, Lloyds Banking Group, Nationwide Building Society, NatWest Group, and Santander, have formed a strategic coalition to develop a financial services-led digital verification service. Operating under the administrative guidance of trade association UK Finance, the high-street lenders are building a secure cross-industry infrastructure that enables consumers to instantly verify personal attributes through their pre-existing mobile banking applications, eliminating the need to upload physical documents such as passports or utility bills.
The decentralised identity architecture allows participating institutions to leverage their verified, regulatory-compliant customer relationships to act as trust anchors. When a customer initiates a transaction with an external third-party merchant or service provider, such as checking into a digital platform, executing a real-estate purchase, or opening a retail account, the banking app acts as a secure identity gateway. The system enforces strict data minimisation protocols under a zero-knowledge framework: customers maintain full cryptographic control, selecting exactly what attribute (such as name, age, or address) to share and with whom, requiring explicit user consent via biometric authentication for each individual inquiry.
The initiative has completed its initial foundational proof-of-concept (PoC) phase, which utilised synthetic data environments to rigorously map out the platform’s multi-party legal liabilities, data privacy compliance layers, and core API technical requirements. To spearhead the next stage of development, the consortium is partnering with Select ID, an Orchestration Service Provider (OSP) fully certified under the government’s UK Digital Verification Services (DVS) Trust Framework. The technical road map dictates the launch of a live, real-world pilot in a controlled sandbox environment within the coming months. Jana Mackintosh, Managing Director of Payments and Innovation at UK Finance, stated that the financial services sector is uniquely positioned to deliver a trusted digital verification layer, driving systemic reductions in identity fraud while accelerating transactional speed across the wider UK digital economy.
What this means for the industry
- Banks are positioning themselves as digital identity providers, leveraging the trust and verification processes they already maintain with millions of customers.
- Customer onboarding could become significantly faster, reducing the need to repeatedly upload documents when opening accounts, accessing services or completing transactions.
- Identity verification may evolve into a new banking utility, creating opportunities for financial institutions to play a larger role in the digital economy beyond traditional financial services.
- The initiative strengthens fraud prevention efforts, allowing consumers to verify attributes through trusted banking channels rather than sharing copies of sensitive documents across multiple platforms.
- Privacy controls are becoming a competitive differentiator, with customers retaining control over exactly what information is shared and with whom.
- Digital identity ecosystems are gaining momentum globally, with banks increasingly viewed as trusted anchors for verifying age, address, identity and other personal credentials.
- The project could accelerate digital transformation across industries, including real estate, telecommunications, e-commerce, government services and financial services.
- Success could establish a blueprint for other markets, encouraging regulators and banking sectors worldwide to explore bank-led digital identity frameworks.
- The long-term opportunity extends beyond verification, potentially enabling seamless onboarding, digital signatures, consent management and secure data sharing across multiple sectors.
- The initiative highlights how banking apps are evolving into broader digital platforms, capable of delivering services that extend well beyond payments and account management.
