# What are electronic signatures? Electronic signatures are a digital means to capture a person's agreement to the contents within a document. They can range from typed names to an electronic image of a handwritten signature, and even to a unique digital code securely linked to a signer. Unlike traditional, wet-ink signatures, electronic signatures utilize various technologies to ensure the signer's identity and consent to the document's terms, making them suitable for a wide range of legal and formal document transactions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
