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.
Modern e-signature platforms like ZiaSign use a multi-layer process:
- Document Upload — Upload PDFs, Word docs, or create from templates
- Signer Assignment — Add signers with email, define signing order
- Field Placement — Drag-and-drop signature, date, initial, and custom fields
- Authentication — Verify signer identity via email, SMS OTP, or ID verification
- Signing — Signers draw, type, or upload their signature from any device
- Sealing — Document is cryptographically sealed with a tamper-evident hash
- 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.
Yes — in virtually every major jurisdiction worldwide.
E-signatures carry the same legal weight as handwritten signatures under:
| Framework | Jurisdiction | Key Provision |
|---|
| ESIGN Act (2000) | United States | E-signatures cannot be denied legal effect |
| UETA (1999) | 49 US States + DC | Uniform state-level recognition |
| eIDAS (2014/2024) | European Union | Three tiers: SES, AES, QES |
| ECA (2000) | United Kingdom | Broad acceptance, sector exceptions |
| IT Act (2000) | India | Digital signatures with Aadhaar integration |
ZiaSign's compliance engine automatically applies the correct legal framework based on signer location, ensuring every signature holds up in court.
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.
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.
