Biometric payment terminals are engineered for payment‑grade accuracy: they meet industry‑approved security certifications, incorporate hardware anti‑spoofing, and (especially with palm‑vein) use an internal biometric that is inherently harder to fake. While the exact numerical FAR/FRR values are not disclosed in the public assets, the documented compliance and technology choices indicate very low error rates suitable for high‑volume retail and financial‑inclusion deployments.
