The present invention pertains to a storage facility containing consumable items that updates an inventory when items are stored, removed and consumed. A product scanner and a computer installed in the facility use RFID technology to determine if an item has been consumed or removed from a locale. Items in the facility have RFID tags attached. The system interrogates the tags and if a tag becomes disabled, displaced or non-existent due to consumption or removal from a locale the system provides instantaneous status. The computer transmits consumption information to a central location for billing, inventory management, market research information and can transmit the same to other processing units such as hand held computers possessed by staff that replenishes the facility. This system prevents used items from being placed back into the housing facility and being incorrectly accounted for as usable/billable and provides for greater room servicing efficiencies.

I claim: 1. A system for tracking inventory comprising: an inventory store; one or more transceivers for interrogating one or more radio frequency identification devices associated with one or more articles; a processor in communication with the transceivers; code operable by the processor to increase the inventory when the one or more articles enter the inventory store; code operable by the processor to initiate a timer when the one or more articles are removed from the inventory store; code operable by the processor to decrease the inventory if one or more transceiver interrogations of a field indicate that the one or more articles removed from the inventory store does not respond to the interrogation or have been used; and whereby if one or more transceiver interrogations of a field indicate that the one or more articles removed from the inventory store have not been used, then the inventory is unchanged for the responding one or more articles provided that the timer has not timed out. 2. The system of claim 1, includes one or more transceiver/repeater combinations to enable interrogation of all associated radio frequency identification devices within a space. 3. The system of claim 1, including a universal product code reader to self purchase articles. 4. The system of claim 1, wherein the radio frequency identification device is adapted to be destroyed as an indication of the removed item being used. 5. The system of claim 1, wherein when the article is opened the antenna is dysfunctional as an indication of article usage. 6. The system of claim 1, wherein an associated pair of radio frequency identification devices are installed on an article. 7. The system of claim 1 wherein the transceiver detects the reception of two associated radio frequency identification devices at different intervals of time as indication that the article has been used. 8. The system of claim 1 wherein two or more transceivers determine if an associated pair of radio frequency identification devices each installed on separate parts of an article produce receptions from different locations as an indication that the article has been used. 9. The system of claim 6, whereupon opening of the article a first radio frequency identification device antenna is made dysfunctional and a second radio frequency identification device antenna remains functional. 10. The system of claim 7, wherein different intervals of time indicate that the separate parts of the article associated with the pair of radio frequency identification devices have been separated. 11. A container comprising a disabling means and a radio frequency identification device antenna integral to a seal whereby the disabling means acts upon the seal to open the container and disable the antenna. 12. A container comprising a cap, a body and a tab, wherein an associated antenna is connected to the tab and the body of the container whereby when the tab is removed it disables the antenna. 13. The container of claim 11 wherein the container is one of a canister or bottle. 14. The container of claim 11 wherein the container is a shrink-wrap container. 15. The container of claim 11 wherein the associated antenna forms a grid. 16. A seal comprising a disabling means and a radio frequency identification device antenna integral to the seal whereby the disabling means acts upon the seal to disable the antenna. 17. The seal of claim 16 wherein the seal is a shrink band seal. 18. A label comprising a disabling means and a radio frequency identification device antenna integral to the label whereby the disabling means acts upon the label to disable the antenna. 19. The label of claim 18 wherein the label is a shrink label. 20. A method for tracking inventory comprising: stocking an inventory store; interrogating a radio frequency identification device associated with one or more articles in the inventory store; processing a communication to record the one or more articles entering the inventory store to increase inventory; initializing a timer when the one or more articles are removed from the inventory store; interrogating the one or more articles removed from the inventory store; and (a) decreasing the inventory for the one or more articles if the radio frequency identification device of one or more articles removed from the inventory store indicate that the one or more articles have been used; and (b) not changing the inventory for the responding one or more articles if the radio frequency identification device of one or more articles removed from the inventory store response indicate the one or more articles have not been used provided that the reentering the one or more articles into the interrogation field or the inventory store occurs before the timer times out. 21. The method of claim 20 wherein the one or more articles have been used is determined if the radio frequency identification device is disabled. 22. The method of claim 20 wherein the one or more articles have been used is determined if the antenna is disabled on one or more articles. 23. The method of claim 20 wherein the one or more articles have been used is determined if an associated pair of radio frequency identification devices installed on an article produce receptions at different intervals of time. 24. The method of claim 20 wherein the one or more articles have been used is determined if an associated pair of radio frequency identification devices installed on an article produce receptions from different locations. 25. The method of claim 20 wherein the one or more articles have been used is determined if a first radio frequency identification device antenna is disabled and a second radio frequency identification device antenna remains functional.
