A verification system has an operational component registry 10 that includes an interface 20, a memory device 30, and a processor 40. Preferably, the interface 20 in the operational component registry 10 communicates the installed identification data 50 from the gaming units 60 to the operational component registry. The memory device 30 preferably stores registered identification data 70 for the gaming units 60. Preferably, the processor 40 in the operational component registry 10 then analyzes the registered identification data 70 and the installed identification data 50 from the gaming units 60, after which enablement of the gaming units is determined based upon the examination of the registered identification data and the installed identification data. An operational component registry 10 may also monitor changes, services, requirements, enablement, and productivity of the gaming units or components of the gaming units.
