A user establishes an account with an account management system and downloads a service application on a user computing device associated with the user. The user enters a service provider location and signs into a service application. A service camera device captures a video feed of one or more users within a visual field of the service camera device and a service computing device compares movement data received from user computing devices at the service provider location against movement of detected objects in the video feed to identify one or more users in the video feed. After identifying the one or more users within the video feed of the service camera device, in response to a particular user initiating a service request at the service computing device, the service computing device identifies the particular user at the service computing device as being within a service area of the video feed.
