US Patent 11755853 Tracking receptacles in physical environments

In implementations of systems for tracking receptacles in physical environments, a computing device implements a tracking system to receive radio wave data describing first radio waves received by a first radio frequency antenna from a radio frequency tag embedded in a physical receptacle within a first region of a physical environment. The first radio waves indicate a unique identifier of the radio frequency tag. The tracking system computes an amount of time that the physical receptacle is within the first region based on the unique identifier of the radio frequency tag. An item is identified that does not include a radio frequency tag based on the amount of time and a unique identifier of the first radio frequency antenna. The tracking system generates an indication of information related to the item for display in a user interface of a display device disposed in a second region of the physical environment.
