What is an electronic signature?

Using electronic signatures to approve and sign documents is quickly becoming standard practice.

Companies and individuals are slowly eliminating the time-consuming process of printing, hand-signing, and scanning documents. Instead, they’re digitally adding their signature directly to documents with only a few clicks.

However, the fast adoption of electronic signatures raises questions.

What exactly is an electronic signature?

Does an electronic signature differ from a digital signature?

Which are the best tools to adopt an electronic signature process?

In this article, we’ll quickly answer these and soon you’ll have a complete understanding of what electronic signatures are, how they work, and how to use them. Also, you can try free electronic signature.

What is an electronic signature?

An electronic signature is any digital mark affixed to the end of a document – a quote, contract, proposal, invoice, etc. – to signify approval. This digital mark can be an image, hand-typed text, or even handwritten using a touch screen.

Whenever you sign for a package on a touch screen or insert a scanned image of your signature into a document, you’re making an electronic signature. Nowadays, many proposals and contracts are created using specific software that allows senders to add signature fields to documents and permits recipients to type in their name easily.

Not all electronic signatures offer the same level of security. An image of a signature inserted into a Microsoft Word document, for example, is less secure than a signature created using an app like PandaDoc, which automatically generates a certificate containing the time and date the signature was completed.

What’s the difference between electronic and digital signatures?

Many people confuse the terms “electronic signature” and “digital signature” thinking they are the same when in fact they are significantly different.

Digital signatures are complex and are a highly secure type of advanced electronic signature. The use of digital signatures requires specific software and the signee must obtain a certificate from an accredited organization called a “Certificate Authority.” They must also first confirm their identity before a certificate is given.

In a nutshell, once somebody obtains a digital signature certificate (which is stored on their computer), they can add it an encrypted format to the document being signed. This encrypted “key” is then verified against a public “key.” There are numerous levels of encryption involved, including the creation of an encrypted electronic document, and the system is underpinned by a technology called the Public Key Infrastructure (PKI).

Are electronic signatures legal and secure?

Yes, electronic signatures are completely legal. Numerous pieces of legislation (in both Europe and the United States) grant electronic signatures the same credibility as handwritten signatures.

Those legislations include:

  • ESIGN (The Electronic Signature in Global and National Commerce Act),
  • UETA (The Uniform Electronic Transactions Act),
  • eIDAS in the European Union.

Furthermore, because electronic signatures almost always involve a digital paper trail, often with numerous certificates attached, they are also fully secure. In most cases, electronic signatures are far easier to verify than traditional pen-and-ink signatures.
