Frequently Asked Questions

What's the difference between a digital signature and a regular signature?

A digital signature is cryptographically secured and includes an audit trail with timestamps, making it legally binding. A regular signature is just a visual mark on the document without verification or legal standing.

Is a digital signature legally binding?

Yes, digital signatures created through our service comply with the ESIGN Act (US), eIDAS (EU), and other international e-signature laws, making them legally equivalent to handwritten signatures.

What information is included in the audit trail?

The audit trail includes timestamps for each action, IP addresses, email verification records, and a detailed log of the signing process. This provides legal proof of who signed and when.

Why does my document need to be uploaded for digital signing?

Unlike our visual signature tool, digital signatures require server-side processing to create cryptographic signatures, generate audit trails, and send verification emails. We ensure your documents are handled securely.
