We have all been there. You receive an important contract, lease agreement, or NDA via email. It requires a signature. The old-school workflow involves: printing the document, finding a working pen, signing it, scanning it back into your computer, and emailing it.
Not only is this terrible for the environment, but it also takes twenty minutes of unnecessary labor. In 2026, creating and applying an electronic signature takes less than fifteen seconds.
The Security of Electronic Signatures
A common myth is that a digital signature drawn with a mouse is not "legally binding." In the vast majority of jurisdictions (including the US under the ESIGN Act and the EU under eIDAS), electronic signatures hold the exact same legal weight as a physical pen-and-paper signature.
