S.C. Code Ann. § 26-5-330 – Electronic signatures; manner of proving; exceptions

(A) An electronic signature satisfies any rule of law requiring a signature or providing consequences if a document is not signed.
(B) An electronic record is signed as a matter of law if it contains a secure electronic signature. Otherwise, a signature may be proved in any manner, including by showing that a procedure existed by which a party must of necessity have executed a symbol in order to proceed further in the use or processing of information.
(C) This section does not apply:
1. (1) to the extent that its application would involve a construction of law that is clearly inconsistent with the manifest intent of the lawmaking body or repugnant to the context of the same rule of law. However, the mere requirement of a "signature" or that a record be "signed" is not by itself sufficient to establish such intent; or
2. (2) to any record that serves as a unique and transferable physical token of rights and obligations, including negotiable instruments and other instruments of title where possession of the instrument is deemed to confer title.
