RFID will never be used against people, except when it is.
Some companies have provisions in their labor agreements that the RFID chips in badges cannot be used to track movements with said evidence being used against employees (i.e. to determine if they are leaving early). Of course, such provisions are honored in the breach on occasion.
It's really not hard to imagine a scenario where RFIDs are mandated in new firearms, and scanners are included with metal detectors as a matter of course.
