Systems for contactless authentication and event processing are provided. In some examples, functionality of a self-service kiosk may be requested. In response, a user may be authenticated and a first interactive user interface may be generated and displayed by the self-service kiosk. A second, different interactive user interface may be generated and transmitted for display by an event processing device. A user may select an option displayed by the event processing device. The user selection may be made via the second interactive user interface. The user selection may then cause the self-service kiosk to execute the selected function.
