S.C. Code Ann. § 26-6-50: Agreement of parties to conduct transactions by electronic means.

(A) This chapter does not require a record or signature to be created, generated, sent, communicated, received, stored, or otherwise processed or used by electronic means or in electronic form.

(B) This chapter applies only to transactions between parties who agree to conduct transactions by electronic means. Whether the parties agree to conduct a transaction by electronic means is determined from the context and surrounding circumstances, including the conduct of the parties.

(C) A party that agrees to conduct a transaction by electronic means may refuse to conduct other transactions by electronic means. This right of refusal shall not be waived by agreement.

(D) Except as otherwise provided in this chapter, the effect of its provisions may be varied by agreement. The presence in certain provisions of this chapter of the words "unless otherwise agreed", or words of similar import, does not imply that the effect of other provisions may not be varied by agreement.

(E) Whether an electronic record or electronic signature has legal consequences is determined by this chapter and other applicable laws.
