A service provider system registers with a service system. A user establishes an account with the service system and the service system establishes a facial template associated with the user account. The service system transmits, to a service provider device at a location, identification information and transmits a shared encryption key to a user computing device associated with the user. The user enters the merchant location carrying the user computing device. The service device receives the encryption key from the user device and decrypts the identification information associated with the user using the encryption key. The user initiates a service request and the service provider device verifies the identity of the user via the facial template associated with the user by generating a facial template based on an image captured of the user to compare against the facial template associated with the user. The service device processes the service request.
