📖 Definition

Electronic Signature (e-signature): An electronic symbol, sound, or process attached to or associated with a contract or record that is adopted by a person with the intent to sign the document.

In simple terms, an electronic signature is a way to sign documents digitally instead of using pen and paper. It can be as simple as typing your name, drawing your signature with a mouse, or using specialized e-signature software.

How Do Electronic Signatures Work?

Electronic signatures work by capturing your intent to sign a document and creating a record of that intent. Here's the typical process:

  1. Document Upload: The document is uploaded to an e-signature platform
  2. Signer Identification: The signer is identified (usually via email)
  3. Signature Creation: The signer creates their signature (typed, drawn, or uploaded)
  4. Application: The signature is applied to the document
  5. Audit Trail: A complete record is created including timestamps, IP addresses, and authentication

Types of Electronic Signatures

1. Simple Electronic Signatures (SES)

The most basic form of e-signature. Includes:

  • Typed names
  • Scanned signatures
  • Checkbox agreements ("I agree")
  • Email signatures

2. Advanced Electronic Signatures (AES)

A more secure form that must be:

  • Uniquely linked to the signatory
  • Capable of identifying the signatory
  • Created using data under the signatory's sole control
  • Linked to the document in a way that detects changes

3. Qualified Electronic Signatures (QES)

The highest level, requiring:

  • A qualified digital certificate
  • Created by a qualified signature creation device
  • Equivalent to handwritten signatures in the EU
