S.D. Codified Laws § 23-24A-8
Any request for final disposition made by a prisoner pursuant to § 23-24A-3 shall also be deemed to be a waiver of extradition with respect to any charge or proceeding contemplated thereby or included therein by reason of § 23-24A-10, and a waiver of extradition to the receiving state to serve any sentence there imposed upon him, after completion of his term of imprisonment in the sending state. The request for final disposition shall also constitute a consent by the prisoner to the production of his body in any court where his presence may be required in order to effectuate the purposes of this agreement and a further consent voluntarily to be returned to the original place of imprisonment in accordance with the provisions of this agreement. Nothing in this section shall prevent the imposition of a concurrent sentence if otherwise permitted by law.
