US Patent 8374926 Inventory control system

The inventory control system includes a portable controller for receiving information relating to an item to be tracked by the inventory control system. The portable controller is in communication with a database that stores the information relating to the item. Preferably, the item includes a readable tag having a unique identification code affixed thereto. A sensor may monitor the general location of the tag after the item is entered into the inventory control system. Furthermore, a tag reader associated with the portable controller is able to pinpoint the specific location of the item via a laser-light beam within the area generally identified by the sensor.
