An item tracking system includes a plurality of items for storage and removal from a compartment. The system includes tags affixed to the items and configured to store identifiers for the items. A tag reader receives data from the tags in response to the items being removed from and returned to the compartment. A sensor in the compartment identifies a state change associated with the compartment. A processor identifies removal of an item with data received by the tag reader, identifies the state change with the sensor after the item is removed and before it is returned, and generates an output with an output device including the identifier corresponding to the item in response to the state change in the compartment.
