Biometrics in Digital Financial Services: An Overview

This report by Dick Clark of Consult Hyperion for FSD Africa provides an analysis of biometric technologies and their application in retail payments and financial services, specifically within emerging economies. It distinguishes between biometric identification (1:N matching) and verification (1:1 matching), concluding that while identification is costly and complex, biometrics are increasingly valuable for strong authentication and customer verification in digital financial services.

• Biometric systems serve two distinct functions: identification (1:N matching), which answers "Who is this person?", and verification (1:1 matching), which authenticates that a user is who they claim to be.
• Biometric identification is often expensive and time-consuming due to the manual processes required for registration and linking biometrics to accounts. Consequently, most financial service and payment applications use biometrics for strong authentication and verification rather than identification.
• The reliability of biometrics varies by type, and some populations may be unable to enrol in specific systems. For example, fingerprint biometrics have a failure-to-enrol rate of 2.5% (25,000 per 1 million users) in the general population, whereas finger vein biometrics have a rate of 0.08% (800 per 1 million users).
• For the mass market, smartphones are the primary platform for biometric deployment, enabling the use of voice, face, or fingerprint recognition. In these mobile applications, security often relies on the integrity of the device and the overall system rather than the biometric alone, as systems are tuned to minimize false rejections to improve user experience.
• Different biometric technologies offer varying trade-offs in accuracy and cost. Fingerprints are ubiquitous and cheap but can be affected by skin imperfections; face recognition is convenient and has no failure-to-enrol rate but can be affected by lighting; and vein patterns (finger and palm) offer high accuracy and are difficult to forge but require more expensive, specialized sensors.
• Standardization and interoperability for biometrics in financial services are very limited compared to government schemes like e-passports. Industry bodies like EMVCo and the FIDO Alliance use an abstracted approach where the biometric verification result is separated from the protocol.
