What is an electronic signature?
An electronic signature is a catch-all term for any electronic process that indicates acceptance of an agreement or a record. The U.S. Federal ESIGN Act defines an "electronic signature" as “an electronic sound, symbol, or process, attached to or logically associated with a contract or other record and executed or adopted by a person with the intent to sign the record.”
