What Are Electronic Signatures?

An electronic signature (e-signature) is any electronic process that indicates acceptance of an agreement or record. Unlike wet-ink signatures, e-signatures capture intent digitally — using typed names, drawn signatures, click-to-sign buttons, or biometric verification.

How E-Signatures Work

Modern e-signature platforms like ZiaSign use a multi-layer process:

1. Document Upload — Upload PDFs, Word docs, or create from templates
2. Signer Assignment — Add signers with email, define signing order
3. Field Placement — Drag-and-drop signature, date, initial, and custom fields
4. Authentication — Verify signer identity via email, SMS OTP, or ID verification
5. Signing — Signers draw, type, or upload their signature from any device
6. Sealing — Document is cryptographically sealed with a tamper-evident hash
7. Audit Trail — Complete chain of evidence: IP addresses, timestamps, device info

With ZiaSign, this entire process takes under 2 minutes. No downloads, no accounts required for signers, no friction.

Are E-Signatures Legally Binding?

E-signatures carry the same legal weight as handwritten signatures under:

ZiaSign's compliance engine automatically applies the correct legal framework based on signer location, ensuring every signature holds up in court.

Types of Electronic Signatures

Simple Electronic Signatures (SES)

The most common type — click-to-accept, typed names, or drawn signatures. Suitable for 90%+ of business documents. ZiaSign's free tier includes unlimited SES.

Advanced Electronic Signatures (AES)

Linked uniquely to the signer with identity verification. Required for higher-value contracts. ZiaSign supports AES with SMS OTP and email verification at no extra cost.

Qualified Electronic Signatures (QES)

The gold standard — equivalent to a handwritten signature in the EU. Requires a qualified certificate from a trusted provider. ZiaSign integrates with qualified trust service providers for QES when needed.
