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.
