(6) Notwithstanding anything in this section to the contrary, a seller who maintains records establishing that it uses electronic means to verify, at least once per calendar year, the validity of its customers' reseller permits need not take a copy of a reseller permit or other documentation or the data elements as authorized in subsection (1), (2), (3), or (4) of this section for wholesale sales to those customers with valid reseller permits as confirmed by the department for all sales occurring within twelve months following the date that the seller last electronically verified the validity of its customers' reseller permits. A seller that meets the requirements of this subsection will be deemed to have met its burden of proving a sale is a wholesale sale rather than a retail sale.
