Abstract: A contactless checkout system with theft detection, and related methods and devices. An inventory of an electronic shopping cart of a user in a retail environment and a virtual inventory of a physical shopping container in possession of the user in the retail environment are maintained. Actions performed by the user, such as placing or removing an item from the physical shopping container, are detected using computer vision. An item associated with each detected action is determined using computer vision based on an inventory storage location at which the detected action occurred. The virtual inventory of the physical shopping container is updated based on detected actions and the associated items. An alert is generated in response to a determination that the virtual inventory of the physical shopping container does not match the inventory of the electronic shopping cart.
