A method and apparatus for controlled dispensing of consumable supply
items, such as office supplies, wherein the quantity of items added or
removed from the apparatus is determined by sensing a change in weight of
items within the apparatus. The apparatus may be in the form of a cabinet
having a plurality of doors, each door having a secured position
preventing access to the items within the cabinet. The cabinet may be
configured to unlock less than all of the doors to allow limited access to
the items based on various factors, such as user identification and item
cost.
