Payments: Visa's chip-on-card biometrics

Visa develops a new spec that enables palm, voice, eye and facial biometrics with chip card payment. (Visa - Tech Matters)

Here’s how it works: Visa’s new architecture enables fingerprints to be securely accepted by a biometric reader, encrypted, and then validated. The specification supports “match-on-card” authentication where the EMV chip card validates the biometric so that it is never exposed or stored in any central databases. Issuers can optionally validate the biometric data within their secure systems for transactions occurring in their own environments, such as their own ATMs.
