Abstract: The invention is a system for dispensing and tracking the use of a plurality of different and discrete consumable items. A dispensing machine is provided which has a supply of the various items to be dispensed arranged in a selected pattern. A program and a memory are in the system to receive and identify data on the user of the machine and the item to be dispensed. The system responds to a request for an item by verifying the authority of the user, generating confirmation of the availability of the requested item, and executing the dispensing of the requested item. The system also generates recordable data regarding the dispensing operation to control the ordering, inventorying and tracking of the dispensed items. A printer can generate a hard copy of the data. Pneumatic matrix switching is also provided to control the selection and dispensing of the consumable items by the system.
