Patent attributes
Systems and methods are provided for authenticating users in connection with transactions. One example computer-implemented method includes, in response to presentment of a payment device in connection with a transaction, identifying, by a point-of-sale (POS) device, the payment device as enabled for facial authentication and retrieving, from the payment device, a reference image. The method also includes capturing, by the POS computing device, via a camera, a facial image of the user presenting the payment device and authenticating the user based on a comparison of the captured facial image of the user to the reference image. The method then includes, in response to successfully authenticating the user: compiling an authorization request for the transaction, appending an authentication indicator to a data element of the authorization request, which indicates that the user was biometrically authenticated, and submitting the authorization request to a payment network.
