Biometrics in Digital Financial Services: An Overview

The report examines the use of biometrics in digital financial services, distinguishing between identification (1:N) and verification (1:1). It concludes that while biometrics are valuable for strong authentication and customer verification—particularly via smartphones for the mass market—they are often too costly and complex for primary customer identification (KYC) at scale. The document evaluates several technologies, including fingerprints, facial recognition, and vein patterns, noting that the choice of biometric depends on the required balance between security, convenience, and transaction speed.

• Biometric technology serves two distinct functions: identification (1:N matching) to determine "Who is this person?" and verification (1:1 matching) to authenticate that a user is the individual they claim to be.
• Biometric identification is generally considered too time-consuming and expensive for most financial services to use as a primary identification tool, leading organisations to continue relying on third-party identification for Customer Due Diligence (CDD).
• For the mass market, smartphones are the primary platform for biometric deployment, supporting voice, face, or fingerprint recognition depending on device capabilities and the environment.
• There are significant failure-to-enrol rates for certain biometrics at a population scale; for fingerprints, approximately 2.5% of 1 million users cannot be enrolled, whereas finger vein technology has a lower failure rate of 0.08%.
• In Japan, approximately 75% of banks have implemented finger or palm vein biometrics in ATMs, driven by regulatory changes that made banks liable for fraudulent withdrawals using stolen or counterfeit cards.
• Biometric systems must balance the False Rejection Rate (FRR) and the False Acceptance Rate (FAR); reducing one typically increases the other, requiring a trade-off based on the specific application's risk and convenience needs.
• Standardisation and interoperability for biometrics in financial services remain very limited compared to other applications like electronic passports (ePassports).
