Many states like Florida and Virginia provide their own background check systems as a substitute for the NICS check with federal approval.

Not according to the Brady Campaign to Prevent Gun Violence

Virginia: State law requires gun buyers to go through a state-based criminal background check in addition to the federal NICS check. This is the best system since it includes checking both state and federal records to prevent criminals and other prohibited people from buying guns.

Well I just read Virginia’s State law 18.2-308.2:2 Criminal History Record Information Check Required For The Transfer of Certain Firearms... law and it clearly says that the dealer must notify the State Police for the background check. The State Police may use the NICS system but the dealer doesn't contact the NICS system directly.
