What is an Electronic Signature?

An electronic signature (or e-signature) is a digital representation of a person's intent to agree to the contents of a document. Unlike wet ink signatures on paper, e-signatures are created and captured electronically, making them faster, more secure, and environmentally friendly.

How Do Electronic Signatures Work?

When you sign a document electronically, several things happen behind the scenes:

  • **Identity Verification**: The system verifies your identity through email, phone, or other authentication methods.
  • **Signature Capture**: Your signature is captured through typing, drawing, or uploading an image.
  • **Document Binding**: The signature is cryptographically bound to the document.
  • **Audit Trail**: Every action is logged with timestamps and IP addresses.
  • Are Electronic Signatures Legal?

    Yes! Electronic signatures are legally binding in most countries around the world:

  • **United States**: ESIGN Act and UETA
  • **European Union**: eIDAS Regulation
  • **United Kingdom**: Electronic Communications Act 2000
  • **Canada**: PIPEDA and provincial laws
  • **Australia**: Electronic Transactions Act 1999
  • Types of Electronic Signatures

    There are three main types of electronic signatures:

    Simple Electronic Signatures (SES)

    The most basic form, including typed names, checkbox acceptances, and drawn signatures. Suitable for low-risk documents.

    Advanced Electronic Signatures (AES)

    Require stronger identity verification and are uniquely linked to the signatory. Used for medium-risk documents.

    Qualified Electronic Signatures (QES)

    The highest level of assurance, requiring a qualified certificate issued by a trusted authority. Required for certain regulated industries in the EU.

    Benefits of Electronic Signatures

  • **Cost savings**: Reduce paper, printing, and shipping costs
