Digital simplicity and customer experience in retail banking: what leading banks do differently

A survey conducted among 1,623 IT decision makers revealed this

In the race to remain competitive, retail banking faces a clear imperative: digital simplicity. The concept has two dimensions: simplifying internal operations using digital and analytical capabilities, and improving customer experience by delivering efficient, fast, and high-quality service.

Customer experience has long been the weak point of financial institutions. While companies like Apple and Amazon have set the bar for seamless digital interactions, traditional banking still faces internal obstacles: complex IT infrastructures, hierarchical processes, and corporate cultures more aligned to the public sector than the digital economy.

But the data is compelling. According to research by the Boston Consulting Group on the world’s top-performing retail banks, those achieving digital and operational excellence enjoy on average 50% more profit per customer before taxes, 30% more customer penetration, and 20% lower operating costs.

These are not marginal gains, they are transformational advantages that compound over time. The banks that have successfully achieved digital simplicity have not done so by incremental improvement. They have fundamentally rethought how banking works, from the customer’s first interaction through to long-term relationship management.

At Namirial, we partner with financial institutions across Europe to implement the digital infrastructure that makes this transformation possible: from AI-powered remote identity verification to qualified electronic signatures and certified document archiving. This article draws on what we have observed in the most successful implementations.

What Separates Leading Retail Banks from the Rest?

1. Financial Returns Driven by Digital Efficiency

Leading banks save approximately 30% per customer in operating costs because they have automated core processes, reduced IT redundancy, and right-sized their workforces. They do not maintain large administrative teams for tasks that can be handled digitally, freeing up resources for higher-value advisory work.

The mechanism behind these savings is straightforward: every process that requires a human to manually handle a piece of paper (printing, scanning, filing, retrieving, posting) has a cost. Multiply that cost across thousands of daily transactions and the total is substantial. When these processes are replaced with digital equivalents: electronic signatures, automated KYC checks, certified email, digital archiving — the per-transaction cost drops to a fraction.

More important than direct cost savings is the capability that digital efficiency creates. When back-office staff are not consumed by paper administration, they can focus on higher-value activities: exception handling, complex customer queries, relationship development. This is not just cost reduction; it is a reallocation of human capital towards its highest use.

2. Excellence in Sales and Digital Customer Service

The shift to digital channels has been dramatic. Transactions and interactions have migrated online: leading banks actively encourage customers to use digital channels for basic transactions, making them easier and sometimes financially incentivising them.

Of the top-performing banks studied by BCG, 66% of clients enrolled using a smartphone. The message is clear: mobile-first onboarding is no longer a differentiator, it is a baseline expectation. Banks that still require customers to visit a branch to open a basic account, or that require printing, signing, scanning and returning documents, are offering an experience that compares poorly to the alternatives their customers encounter daily in retail, travel and media.

At the same time, customers still seek in-person interaction for complex decisions: mortgage applications, investment planning, major financial transitions. The role of the branch is not disappearing, but it is being transformed. New branch procedures focus on value-added advisory services, paperless workflows (including electronic signatures for any documentation generated during the meeting), videoconferencing, and appointment management. Employees devote the majority of their time to preparation and client-facing work, not paper-based administration.

The best digital banks have achieved a coherent omnichannel experience where the customer can move seamlessly between digital and physical channels without repeating themselves, losing context, or starting processes over. This requires unified customer profiles, synchronised across all systems, accessible in real time to every staff member.

3. Automating Back-Office and Onboarding Processes

Among the banks studied by BCG, those that automated their back-office processes consistently outperformed those that did not. The difference in account-opening productivity is stark: while leading banks open around 10,000 accounts per year per employee, middle-ranking banks open only 4,000.

The cycle time for unsecured loan origination has fallen dramatically with automation, from 2 hours to under an hour in top-performing institutions. For most retail banks, introducing paperless tools and automated onboarding systems remains a work in progress.

The key bottlenecks are typically identity verification, document collection, and signature. In a traditional bank branch, each of these steps involves physical presence, paper documents, wet ink signatures, and manual filing. Automating them means:

  • Remote identity verification: the customer completes KYC from their phone, uploading their identity document and completing a biometric liveness check, all verified in under two minutes by AI
  • Electronic signature: contracts, mandates, and account opening documents are signed electronically, with full legal validity under eIDAS, from any device
  • Automated compliance checks: sanctions screening, politically exposed persons (PEP) checks, and risk scoring run automatically in the background
  • Digital archiving: all signed documents are archived with qualified timestamps, legally valid for decades, and instantly retrievable

Electronic signatures, automated KYC workflows, and qualified digital archiving are no longer optional additions, they are core operational infrastructure for banks that want to compete on speed and client experience.

4. Unified Customer Data and Analytical Intelligence

Leading banks have simplified their technical infrastructure by consolidating overlapping platforms and retiring redundant systems. They use analytical and data management tools to integrate all customer information into a single platform, giving advisors a complete picture of each client across all touchpoints — whether the client is at a branch, on mobile, or online.

This unified view of the customer translates into products and services better aligned to real behaviour, needs, and preferences, driving both loyalty and revenue.

Data unification is harder than it sounds. Many banks have accumulated dozens of separate systems over decades of acquisitions, regulatory requirements, and technology cycles. Each system has its own data model, its own definitions of “customer” and “account,” and its own team of people who understand and maintain it.

The path to data unification requires both technical work (building integrations, establishing master data management, creating a single customer ID that spans all systems) and organisational work (establishing data governance, assigning data ownership, training staff on new tools). It is a multi-year programme, but the banks that have completed it hold a substantial and durable competitive advantage.

The Impact of eIDAS 2.0 on Retail Banking

The arrival of eIDAS 2.0 and the European Digital Identity Wallet (EUDI Wallet) will create new opportunities, and new compliance obligations — for retail banks.

From July 2027, all regulated entities including financial institutions must accept the EUDI Wallet as a means of identification. This means that a customer presenting their EUDI Wallet during onboarding must be accepted, and the bank’s systems must be able to process wallet-based identity credentials.

For forward-thinking banks, this is an opportunity to dramatically simplify and accelerate onboarding. A customer with an EUDI Wallet can share verified identity attributes (name, address, date of birth, nationality) that have already been verified by a government authority. The bank does not need to re-verify this information through its own KYC process; it can rely on the wallet’s attestation. Onboarding time can drop from days to minutes.

Banks that begin building EUDI Wallet integration now will be ready to capture these benefits when the wallet ecosystem reaches scale, rather than scrambling to comply at the last minute.

The Namirial Advantage for Retail Banking

Namirial’s Digital Transaction Management platform gives banks the tools to achieve digital simplicity across the full customer lifecycle:

  • Secure remote onboarding with AI-powered identity verification aligned with ETSI TS 119 461 v2.1.1, covering document OCR, liveness detection, facial recognition, and MRZ validation for documents from over 200 countries
  • Qualified electronic signatures for all contract types, with biometric capture, qualified timestamp, and complete audit trail
  • Certified electronic delivery (registered email) for all legally sensitive communications
  • Qualified long-term archiving ensuring documents retain their legal validity for decades
  • EUDI Wallet integration through Namirial Wallet Gateway, enabling banks to accept wallet-based identity credentials for onboarding and authentication
  • API-first architecture allowing all capabilities to be embedded into existing core banking systems, CRM platforms, and mobile apps

Banks that have not yet automated their customer-facing and back-office processes are already falling behind the institutions that have. The question is not whether to transform, but how quickly to move, and with which partners.
