What is an Electronic Signature?
An electronic signature, or e-signature, is a legal concept, much like its paper equivalent. It is 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. E-Signature laws and regulations vary from country to country, but most share the same basic principles around signing documents.
