Abstract: Techniques for improving efficiency of an inventory system are described. In an example, operations of the inventory system may involve reading a marker attached with an item. The item may be available from an inventory space. Based on instructions of a computing management module of the inventory system, information about the item may be printed at a first location on a medium. Based on the instructions, a layer of disappearing ink may also be applied over at least a portion of the information. Further, based on the instructions, an identifier of the item may be printed at a second location on the medium. The medium, including the printed information, the layer of disappearing ink, and the printed identifier may form the marker.

Abstract: Techniques for improving efficiency of an inventory system are described. In an example, based on instructions of a computing management module of an inventory system, a trigger associated with reading a marker may be triggered. The marker may be attached with an item available from an inventory space and may encode information about the item. The marker may be configured to present, in response to receiving a non-visible light wavelength, a visible indication of an attachment location of the marker. Further, based on the instructions and at least in part on the trigger, a light source may emit the non-visible light wavelength. The emission of the non-visible light wavelength may cause the marker to respond with the visible indication of the attachment location. The visible indication may facilitate a read of the marker by a reader of the inventory system to trigger an inventory action.
