"European palm biometrics startup Handwave has announced an expanded agreement with Visa. A release says the agreement integrates Visa’s tokenization and authentication technologies into Handwave’s model for safe, seamless card onboarding. Building on a prior collaboration focused on integrating Visa’s Token Management Service (TMS), the new Handwave integration will enable Visa to securely link cards to a user’s palm biometrics, replacing sensitive data with secure digital tokens."
