An electronic signature in PDF, also known as a digital signature, is a digital representation of a handwritten signature that can be attached to electronic documents. It serves the same purpose as a traditional wet signature, providing authentication and intent to sign.
Electronic signatures have become increasingly important in modern business and communication. They offer numerous benefits, including increased security, convenience, and reduced costs. One of the key historical developments in this area was the introduction of the Electronic Signatures in Global and National Commerce Act (ESIGN) in 2000, which established the legal validity of electronic signatures in the United States.
