Electronic signatures on letters represent a legally binding method of verifying the identity of the sender. They are used to signify intent to be bound by the contents of the letter, and provide an easy and secure means of authentication. By signing electronically, an individual is certifying that they have read the content of the letter and approve of its contents, which then makes the document enforceable according to law. Electronic signatures allow for shorter turnaround times, greater accuracy, and improved process consistency. With electronic signatures, businesses can conduct their transactions safely, securely, and with confidence.
