    Inventors: John Lie-Nielsen, Tibor Szenti
  • Patent number: 6882282
    Abstract: A system and method of tracking the location of stored objects, such as keys, that maintains object-tracking data in a remote data storage that is accessible via the Internet. A storage container selectively provides access to one or more uniquely identifiable objects stored within, such as keys, through an access control that gathers the tracking data generated from the removal and return of each object. The access control further includes an output for selective transmission of the object-tracking data over a network to a remote data store that stores and provides access to the stored object-tracking data to other computer devices on the Internet. The data store can provide the object tracking data to other computer devices, visually summarize the data in a report to a user, and can alter data stored at the access control.
