May be a bit of the wrong place, but perhaps some kind of component that accepts items and sends a signal when an item is inserted into it or scanned on it that it is keyed to. First use of an item on it would bind it to that item in much the same way the first scan of a card reader binds it to that ID. Basically, a way to set an item as a "key" to whatever setup you have.
