S.C. Code Ann. § 61-2-110

The department must accept checks, in addition to any other method of payment it considers appropriate, in payment of the fees due for a license or permit. If the check is dishonored, the department may suspend the license or permit without notice or a hearing until the applicant makes the payment in a form satisfactory to the department and pays a reinstatement fee of fifty dollars. The department may retain the reinstatement fee in order to offset the cost of this provision.
