Abstract: A system for storing and electronically monitoring the locations of keys and other articles, and providing a printed record of transactions involving the stored articles. The articles are held on digitally coded article holders which are stored on a storage panel and electronically scanned to determine the identity of the article at each storage location on the panel. When an authorized user of the system enters his user code and makes a request for one of the articles, an indication light is energized to indicate the location of the requested article. If the article is absent, the system displays the user code of the authorized user in possession of the missing article. A printer in the system operates to provide a printed record of which users removed and returned which articles at which times. An optional scale weighs articles such as pharmaceuticals to determine the weight of the contents that are removed.
