Traditional authentication methods such as passwords and one-time codes are no longer strong enough to protect financial institutions against sophisticated fraud. Deloitte estimates synthetic identity fraud could reach $23bn in losses by 2030, highlighting the urgency for banks to strengthen defences.
SymphonyAI, which offers AI-powered financial crime prevention solutions, has delved into why financial institutions cannot ignore biometrics.
Biometrics are proving to be a critical solution. They go far beyond simple fingerprint scans, encompassing facial and voice recognition as well as behavioural biometrics, which analyse how users type, swipe, and interact with their devices. Unlike static logins, these tools provide continuous authentication, detecting anomalies throughout a session and locking out fraudsters before they can act.
For mid-tier banks, adopting biometrics does not demand vast budgets, it said. Initial steps could include integrating behavioural biometrics into digital channels, enabling app-based fingerprint and facial recognition, or introducing voice verification in call centres. Alongside implementation, institutions should communicate clearly to customers that these measures are about safeguarding them as much as the bank.
As McKinsey has noted, investing in digital trust can unlock as much as 10% annual revenue growth. For banks, biometrics represent not just stronger security but a foundation for deeper customer trust and loyalty. Fraudsters have already moved beyond passwords; now it’s time for financial institutions to do the same.
