MasterCard In Your Face
Security experts have raised concerns about the possible introduction of credit card facial recognition, calling for extra layers of security. One said he was concerned scammers could take a photo of somebody and present it to the camera, and the phone would unlock.
MasterCard says its app gets past this by asking users to blink to prove that they are human and not a still image.
The card company is exploring facial recognition as an alternative to SecureCode, its security software that asks online shoppers for a password to make purchases.
