At the Mobile World Congress in Barcelona, G+D Mobile Security and Samsung showcased a banking authentication product that relies on biometrics instead of passwords. The technology also meets the revised digital payments standards under the new European Payment Services Directive, or PSD2.

The dual interface cards, usable at existing payment terminals in the country, feature fingerprint authentication and no limits on battery life and transactions. Customers soon could be able to enroll in the program via self-service.

The International Biometrics and Identity Association issues a blistering white paper that seeks to refute criticisms leveled at the facial recognition authentication program being deployed in U.S airports. The paper covers the justification and efficiency of Biometric Exit, among other topics.

Digital IDs offer a promising solution for re-securing American identities: They can be verified offline using tamper-proof digital signatures, and securing access to digital credentials with PIN or biometrics enables strong protection against fraudsters.

A consumer suit brought under an Illinois biometric privacy law gains sympathy from the judge, and shows the challenges that still face major companies as they try to win over advertisers and consumers with new personalization features. And now Google is experiencing a hurdle with similar technology.
