What Does Signature Mean?
A signature is a way for someone to show their agreement, approval, or identity—usually by writing their name. In the digital world, a digital signature works the same way. It’s like signing a piece of paper, but on a screen.
When someone draws their signature on a form using their mouse, finger, or stylus, it becomes part of that form. This is useful for things like:
- Approving a service or product
- Agreeing to terms and conditions
- Signing contracts or applications
Adding a signature to your forms makes them feel more official and trustworthy. It also helps you collect clear proof that someone agreed or approved something.
What is Digital Signature?
A digital signature is an electronic way to sign a document or form. Instead of using a pen on paper, people can draw or type their signature on a screen—using a mouse, touchscreen, or stylus.
It helps prove that a person has read and agreed to something. You’ve probably seen it when signing for a package or filling out a form online.
There are two common types of digital signatures:
- Drawn Signatures – The user draws their signature, just like they would on paper.
- Encrypted Digital Signatures – These use advanced technology to lock the signature with a unique code for extra security (used more in legal or business documents).
For most websites using Contact Form 7, drawn signatures are perfect. They’re simple, fast, and work great for things like approval forms, agreements, bookings, and more.
Traditional Signature vs Digital Signature
A traditional signature is handwritten using a pen on paper, while a digital signature is created electronically—often on a screen or device. Both are used to verify identity and agreement, but the way they work is quite different.
| Feature | Traditional Signature | Digital Signature |
|---|---|---|
| Method | Signed by hand using a pen | Drawn or typed using a mouse, finger, stylus, or keyboard |
| Medium | Physical documents (paper) | Digital documents (PDF, web forms, etc.) |
| Accessibility | Requires in-person or physical delivery | Can be signed from anywhere with an internet connection |
| Speed & Convenience | Slower – involves printing, signing, scanning, and sending | Instant – sign and submit online within seconds |
| Cost Efficiency | Printing, scanning, and delivery can add up | No printing or mailing costs – fully online |
| Security | Easier to forge or tamper | Can include encryption, authentication, and timestamps |
| Verification | May require manual verification | Automatically stores signer’s data (IP, time, email) |
| Legality | Legally accepted in most places | Legally recognized in many countries under laws like ESIGN, eIDAS, and IT Act |
| Use in Online Forms | Not possible without uploading a scan | Integrates using plugins like Contact Form 7 Signature Addons |
| Environment-Friendly | Requires paper, ink, and storage space | 100% paperless and eco-friendly |
| Storage & Backup | Stored in physical files (can be lost or damaged) | Secure cloud or digital storage with easy backups |
