Fraud-related losses have escalated dramatically in recent years. In the US, for example, consumers lost $12.5 billion to scams in 2024—a 25% increase from 2023. Verified data from the US Federal Trade Commission reveals specific vulnerabilities that banking apps must address:

1 - Critical loss categories

• Bank transfers and cryptocurrency: Combined losses exceeded $3.4 billion in 2024, with bank transfers accounting for $2 billion and cryptocurrency $1.4 billion.

• Social media-initiated fraud: Consumers lost over $1.9 billion to scams that started on social media platforms.

• Government imposter schemes: Losses increased from $171 million (2023) to $789 million (2024).

Similar trends are seen worldwide, underscoring the need to strengthen and adapt current banking app security measures for the evolving threat landscape.

2 - Digital authentication requirements

The following measures, outlined in the Digital Identity Guidelines (NIST SP 800-63B) published by the National Institute of Standards and Technology in the US, should be implemented by banking institutions to bolster digital authentication and lifecycle management. 

• 12-hour re-authentication: All banking sessions should require identity reverification every 12 hours regardless of user activity, to address session hijacking vulnerabilities.

• Protected communication channels: Encrypted, authenticated channels between biometric sensors and verification systems prevent man-in-the-middle attacks.

• Dual-factor enforcement: Combining "something you have" (device/token) with "something you are" (biometric), as biometrics alone do not constitute acceptable digital authentication secrets³.


3 - Enhanced biometric security

Current vulnerabilities

Industry reports indicate biometric spoof attempts have increased significantly in recent years, with voice biometrics showing particular vulnerability to deepfake attacks, making them less suitable for high-security banking applications.

Recommended biometric stack

• Primary authentication: Facial recognition combined with government document verification provides stronger identity assurance than voice-based systems. Implementation should include ISO/IEC 30107-3 certified liveness detection with 3D depth scanning to counter AI-generated spoofing attempts.

• Multi-modal redundancy: Combining fingerprint and facial recognition creates multiple failure points for attackers. Biometric templates should be stored locally on devices rather than in centralized databases.

• Presentation attack detection: Real-time deepfake detection systems are essential given the documented increase in AI-powered spoofing.


4 - Risk-based authentication engine

Core components

• Device fingerprinting: Establish behavioral baselines for each user's device interactions, including typing patterns, navigation habits, and application usage patterns.

• Geolocation analysis: Compare current login patterns against historical data to identify impossible travel scenarios.

• Transaction velocity monitoring: Flag rapid successive transactions or unusual spending patterns that deviate from established user behavior.


5 - AI and machine learning integration

Current capabilities

• Risk assessment engines: Machine learning algorithms analyze transaction patterns and user behavior to generate real-time risk scores.

• Fraud detection: AI systems can achieve high accuracy rates in threat detection while reducing false positives compared to rule-based systems.

Critical Limitations

• Adversarial vulnerabilities: Fraudsters increasingly use generative AI to create synthetic identities designed to fool defensive AI systems.

• Model drift: AI accuracy degrades over time without continuous retraining.

1 - The business case for inclusive banking

When the European Accessibility Act became fully enforceable on June 28, 2025, it marked a turning point for digital banking. Rather than viewing accessibility as regulatory compliance, forward-thinking banks recognize it as a pathway to untapped markets worth hundreds of billions in annual spending power.

According to the World Health Organization, 1.3 billion people—16% of the global population—live with significant disabilities. In the UK alone, this demographic controls £274 billion in annual spending power, dubbed the "Purple Pound".

2 - The strategic opportunity

Banking apps that prioritize accessibility capture customer loyalty in ways traditional institutions cannot match. Users who struggle with standard interfaces but find accessible alternatives become advocates, influencing family and friends’ banking decisions far beyond the immediate user base.

3 - The European Accessibility Act framework

The Act establishes comprehensive requirements affecting all EU operations and companies serving European customers. Organizations face substantial penalties for non-compliance: fines reaching €35 million or 7% of global turnover, restricted product access, or suspended EU operations.

4 - Technical standards and implementation

Design requirements:

• Color and visual design: Banking apps must maintain minimum 4.5:1 color contrast ratios for normal text and 3:1 for large text.

• Navigation and interaction: Every interactive element requires keyboard accessibility, enabling users who cannot operate touchscreens to complete full banking transactions

• Assistive technology integration: Banking apps must work seamlessly with screen readers like NVDA, JAWS, VoiceOver, and TalkBack


5 - Implementation best practices

Design-first approach: Building accessibility into initial design phases reduces costs substantially compared to post-development remediation while creating superior user experiences for all customers.

Testing and validation: Comprehensive validation requires testing with actual disability community members throughout development cycles, focusing on core banking workflows—account setup, fund transfers, bill payments.

In addition to the accessibility measures described above, user experience design frameworks should incorporate the following considerations.

1 - Neuroscience-driven interface architecture

Financial decisions are among the most important life-shaping decisions people make, yet cognitive constraints and financial literacy limitations cause many decisions to violate sound financial principles.

2 - Neuropsychological design principles

• Working memory optimization: Following Miller's Law, financial interfaces should present no more than 7±2 primary navigation options to prevent cognitive overload during high-stress financial decisions.

• Dual-coding theory application: Critical financial information should be presented through both visual and textual channels, enhancing comprehension and reducing errors.

• Stress-response mitigation: Banking interfaces must provide extra-clear confirmation messages and reduce uncertainty during transactions.

• Behavioral pattern recognition: Banking UX design must account for cognitive biases in financial decision-making.


3 - Behavioral economics integration

The goal is designing interfaces that work with human psychology:

• Reduce fee shock: Show the value users get, not just what they pay.

• Avoid misleading comparisons: Present account information without confusing reference points.

• Encourage realistic thinking: Display complete financial pictures, not just positive news.

1 - The reality guide for banking AI implementation

Build your data foundation first: Before implementing any AI features, banks must invest substantial time building robust data infrastructure. Research indicates that most AI projects fail if data infrastructure is not ready.

Essential components include:

• Cloud-based data lake with historical transaction data
• API management layer for real-time personalization
• Automated data quality monitoring achieving high accuracy before training AI models
• GDPR Article 22 "right to explanation" capabilities
• Model risk management frameworks with automated bias detection

Implement AI features gradually: Begin with simple, measurable use cases rather than comprehensive transformation:

• Transaction categorization
• Basic spending pattern analysis
• Simple chatbot functionality for routine inquiries
• Predictive features like cash flow alerts and personalized product recommendations

Scale responsibly with comprehensive governance: Sustainable AI implementation requires robust governance frameworks that balance innovation with risk management, regulatory compliance, and operational stability.

2 - Emerging AI developments in banking

Financial institutions are exploring advanced AI applications beyond traditional automation, including systems capable of more autonomous decision-making within defined parameters. While these developments are in early stages, they represent potential evolution in how AI might assist with routine banking operations, fraud detection, and customer service functions. However, such applications require careful consideration of regulatory compliance, risk management, and customer disclosure requirements before implementation.

1 - Core banking services

Core banking services must deliver seamless, secure, and intelligent financial experiences:

2 - Customer engagement and contact center integration: the foundation of banking excellence

The strategic imperative of human connection

While digital banking capabilities often receive primary focus in strategic planning, customer engagement through integrated contact center services represents the fundamental cornerstone that determines overall banking experience quality. The most sophisticated mobile banking app becomes a liability if customers cannot seamlessly access human assistance when encountering problems, experiencing fraud, or managing complex financial emergencies.

Industry research consistently demonstrates that the majority of banking customers require human assistance for complex transactions, making seamless digital-to-human handoff capabilities absolutely essential for customer retention and satisfaction⁹.

Customer engagement requirements

Contemporary banking customer engagement must function as a unified ecosystem rather than separate digital and human channels:

• Real-time context sharing: Seamless data flow between mobile applications and agent desktop systems

• Advanced interaction capabilities: Screen sharing capabilities where agents can view customer mobile app sessions in real time

• Proactive engagement: AI-powered systems that can predict when customers may need assistance

• Multichannel consistency: Ensuring customer service quality remains consistent across all interaction points

Performance impact on digital banking success

Customer engagement quality directly affects digital adoption rates and overall satisfaction with mobile banking platforms. Banks with poor digital-to-human escalation processes experience substantially higher app abandonment rates during complex transactions.

Conversely, financial institutions with seamless omnichannel customer engagement report that customers who receive exceptional human support during their first complex transaction become substantially more likely to use digital channels for routine activities.

The business case for excellence in customer engagement

Research from leading customer experience firms shows that financial institutions with superior customer engagement integration achieve:

• Substantially higher customer retention rates

• Better cross-selling success compared to digital-only approaches

• Higher customer lifetime value
