S.D. Codified Laws § 34-20F-6
If offering for sale loose leaf incense, a retailer shall, before making such a sale, require and make a record of the identification of the person purchasing the product. For purposes of this section, the term, identification, means a document issued by a governmental agency which contains a description of the person or a photograph of the person, or both, and gives the person's date of birth, such as a driver license, passport, or military identification card. The retailer shall maintain the record of identification, including the purchaser's name and date of birth. On August 1, 2012, and no later than the fifth day of every month thereafter, the retailer shall send any such records to the Office of the Attorney General. No retailer may use or maintain the record for any private or commercial purpose or disclose the record to any person, except as authorized by law. The retailer shall disclose the record, upon request, to a law enforcement agency for a law enforcement purpose.
