An electronic signature, also known as a digital signature or e-signature, refers to an electronic record that is used to sign documents or contracts. It can be in various forms such as typing one's name on a computer keyboard, using a stylus pen on a touch screen device, or clicking on an icon. An electronic signature carries the same legal weight and validity as a traditional handwritten signature, and is used to authenticate and verify the identity of the signatory. It also provides evidence that the document has been signed by the person intended, and helps to prevent fraudulent activities such as forgery or tampering with electronic documents.
