A hardware system enables computer network interaction between network identity services and account-based service applications. In some examples, the network identity service biometrically identifies people. The network identity services and/or account-based service applications interact to exchange data in order to monitor, track, initiate, and/or cooperatively and/or individually perform various functions while protecting data that should not be shared and minimizing communication network usage and hardware and software resources. This interaction enables both to accomplish more and different tasks than they could individually while improving operational efficiency of hardware and software components of both.
