What Is an Electronic Signature and How Does It Work?
If you've ever signed for a package delivery, clicked “I Agree” on a website, or drawn your signature on a touchscreen, you've used an electronic signature. But what exactly is an electronic signature, how does it work, and is it legally binding?
In this beginner-friendly guide, we'll answer all these questions and explain everything you need to know about electronic signatures in simple, plain language.
What Is an Electronic Signature?
An electronic signature(also known as an e-signature) is any electronic mark, symbol, sound, or process that is attached to or logically associated with a document and that shows a person's intent to sign that document.
In simple terms, an electronic signature is the digital equivalent of a handwritten signature. Common examples include:
- A signature you draw with your finger on a phone or tablet
- A signature you draw with your mouse on a website
- A typed name at the bottom of an email or document
- A scanned image of your handwritten signature pasted into a document
- Clicking an “I Accept” or “I Agree” button online
How Do Electronic Signatures Work?
Electronic signatures work by capturing your intent to sign a document through a digital action. The exact technology depends on how the signature is created:
Drawn Signatures
When you draw your signature on a touchscreen or with a mouse, the tool captures the strokes as an image. In client-side tools like LazySign, this image is created entirely in your browser using the HTML5 Canvas API — nothing is sent to a server.
Typed Signatures
A typed name at the bottom of a document serves as an electronic signature. The act of typing and submitting demonstrates intent to sign.
Click-to-Sign
Clicking a button labeled “I Accept” or “Sign” is a valid electronic signature. The click event is recorded along with metadata like the timestamp and IP address.
Certificate-Based Signatures
Advanced digital signatures use cryptographic certificates to verify identity and detect tampering. These require a digital certificate issued by a trusted authority.
Are Electronic Signatures Legally Binding?
Yes. Electronic signatures are legally binding in most countries around the world under various laws and regulations:
- United States: ESIGN Act (2000) and Uniform Electronic Transactions Act (UETA)
- European Union: eIDAS Regulation (2016)
- Canada: PIPEDA and Uniform Electronic Commerce Act
- Australia: Electronic Transactions Act (1999)
- United Kingdom: UK eIDAS Regulation
- India: Information Technology Act (2000)
- Japan: Electronic Signatures and Certification Business Act
- Brazil: Medida Provisória 2.200-2/2001
