S.C. Code § 7-13-1880
As soon as the polls of election are closed, the managers shall immediately lock or seal the voting machine against further voting and open the counter compartment in the presence of all persons who may be lawfully present at the time giving full view to the results, and they shall canvass and announce the results, including the votes recorded for each office on the independent ballots. They shall also announce the vote upon every amendment, proposition, or question voted upon, as provided by Section 7-13-110. The vote as registered shall be duly certified and sworn to and returned and filed as provided in this title for returning and filing election returns. No tally sheets or return blanks, as required by law for use in voting precincts in which paper ballots are used, need be furnished or used when voting machines are used, and no ballots need to be returned with the machine results except the provisional and failsafe ballots.
