An inventory-tracking unit associated with a storage unit holding items to be dispensed includes a card reader to read an access card issued to a user and a recorder to record data from items removed from the storage unit. A processor communicates with a sensor in the storage unit and with the card reader and recorder. The sensor provides item data to the processor that is associated with items removed from the storage unit. The processor compares item data received from the sensor with the data recorded by the recorder to detect coincidence. The processor generates a transaction upon coincidence of item data received from the sensor with the recorded data. A communications interface transmits the transaction to a remote site.
