Abstract: Systems, machines, methods, and computer-readable media are disclosed for detecting an event at a self-checkout (SCO) machine, determining that the event is an item-identifying event, triggering capture of image data of the item identified by the item-identifying event responsive to detecting the event and/or responsive to determining that the event is an item-identifying event, and generating enhanced item identification data that associates the captured image data with identifying information of the item. The enhanced item identification data may be stored in one or more datastores, which may include a local datastore in a retail environment in which a self-checkout machine is located or a remote datastore such as cloud-based data storage.
