In an effort to prevent fraud and ease the secure payments process, Visa has introduced a specification that can authenticate EMV chip card transactions using multiple forms of biometrics.
The Visa architecture enables fingerprint acceptance by biometric readers. This framework, which also encrypts and validates each transaction, can enable palm, voice, iris and facial recognition as well.
The specification supports "match-on-card" authentication, in which the EMV chip card validates the biometric authentication data without ever exposing or storing it in any central database. Issuers will have the option of validating the biometric data within their secure systems for transactions that occurr in their own environments, such as their own ATMs.
