What Is Electronic Signature?
An electronic signature (e-signature) is any electronic symbol, sound, or process attached to or associated with a document that a person adopts with the intent to sign. It serves the same legal purpose as a handwritten signature but is created and applied digitally.
Electronic Signature Explained
Electronic signatures encompass a broad category of methods used to indicate agreement or approval on digital documents. They can be as simple as typing your name into a signature field, drawing your signature with a mouse or finger on a touchscreen, or clicking an "I Agree" button. The key legal requirement is that the signer must demonstrate clear intent to sign.
In the United States, electronic signatures are legally recognized under the ESIGN Act (2000) and UETA (1999). In the European Union, the eIDAS regulation provides a framework with three tiers of electronic signatures: simple, advanced, and qualified. Most everyday business transactions require only a simple electronic signature.
Modern e-signature platforms like eSignTap add layers of security and evidence collection on top of the basic signature. These include audit trails, signer authentication, timestamps, and tamper-evident seals that make electronic signatures not only convenient but often more legally defensible than traditional wet signatures.
