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.
