An e-signature, or electronic signature, is a digital version of a handwritten signature that allows individuals to sign documents online. It can take various forms, such as a typed name, a scanned image of a signature, or a unique digital code. E-signatures are commonly used in business transactions, contracts, and legal agreements to streamline processes and reduce paperwork. E-signatures are legally recognized in many countries, including the United States and European Union, thanks to laws like the ESIGN Act and the eIDAS Regulation. They provide a secure and efficient way to sign documents, ensuring authenticity and integrity while saving time and resources.
