US Patent 10474879 Automatic hands free service requests

A service device processes a service request using account information of a user. The service device captures a first image of the user, generates a first user facial template based on the first image, and transmits the first user facial template with the account information to a service processing system. The user arrives at the service device to initiate a subsequent service request. The service device captures a second image of the user and generates a second user facial template based on the second image and searches for the first facial template matching the generated second facial template. The service device transmits a first stored matching facial template to the service processing system and a request for account information. The service device receives stored account information associated with the stored first facial template from the service processing system. The service device processes the subsequent service request using the account information.
