Difference Between Wet, Typed, Stamped, and Digital Signatures

Difference Between Wet, Typed, Stamped, and Digital Signatures (Quick Answer)

Wet signatures are handwritten on paper, typed signatures are electronically entered text, stamped signatures usually use an image or stamp mark, and digital signatures use cryptographic verification.

The short version is:

• Wet = handwritten
• Typed = electronic text
• Stamped = image or mark
• Digital = secure cryptographic signing

They may all look like “signatures,” but they do different jobs.

Wet Signatures

A wet signature is the traditional handwritten signature on paper.

It is still common for:

• Official paper forms
• Physical contracts
• Documents that require in-person signing

It is familiar, but not always the fastest option.

Typed and Stamped Signatures

Typed signatures are often used when a person enters their name electronically.

Stamped signatures usually mean a signature image or stamp is placed on the document.

These are useful for:

• Fast approvals
• Basic forms
• Internal documents
• Simple sign-off workflows

They are convenient, but they do not provide the same verification as a digital signature.

Digital Signatures

A digital signature adds identity and integrity checks.

It helps confirm:

• Who signed
• Whether the file changed later
• Whether the signature can be verified

That is why it is often used for more sensitive or formal documents.

Best Practice Summary

If you want the short version:

• Wet signatures are handwritten on paper
• Typed and stamped signatures are electronic but simpler
• Digital signatures add cryptographic verification
• Choose the method based on the document’s importance
• Do not assume all signature types offer the same trust level

That is the simplest way to compare wet, typed, stamped, and digital signatures.

FAQ

Are stamped signatures legally the same as digital signatures?

Not necessarily. They are different methods with different levels of verification.
