All over the world , almost all of the products have a "Bar Code"
identifier , which approximately may be considered "Unique" .


Is there a possibility to associate PCI and USB and other devices with
their bar code identifiers  ?


For computers assembled already , it will be necessary to ask to sellers to
supply bar codes of included devices .

By using product bar codes , I think , it will be possible to identify
uniquely a large number of devices .

In that way , it will also be possible to define device characteristics
correctly even they lie about their parameters .
