An E-Signature is a digital version of a handwritten signature that allows individuals to sign documents electronically. 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 online transactions, contracts, and agreements, making the signing process faster and more efficient. E-signatures are legally recognized in many countries, including the United States and European Union, under laws like the Electronic Signatures in Global and National Commerce Act (ESIGN) and the eIDAS Regulation. They enhance security and reduce paper usage, contributing to a more sustainable approach to document management.
