An electronic signature, often referred to as an e-signature, is a digital version of a handwritten signature. It is used to confirm the authenticity of a document or agreement in electronic form. E-signatures can take various forms, including typed names, scanned images of handwritten signatures, or even unique digital codes. These signatures are legally recognized in many countries, making them a convenient alternative to traditional paper signatures. They streamline processes in various industries, such as real estate, finance, and legal, allowing for faster transactions and reduced paperwork.
