Dual Signature Support
Sign documents with both digital and handwritten signatures for enhanced legal validity. Our platform supports multiple signature types on a single document, allowing you to combine the convenience of digital signatures with the traditional authenticity of handwritten ones. Perfect for documents that require both personal and organizational signatures, or for meeting specific legal requirements across different jurisdictions.
AI Identity Verification
Confirm the signer’s identity before they sign. Our AI first performs liveness and anti-spoof checks to detect a real person in the camera (not a photo, mask, or replay) using motion prompts, glare detection, and real-time analysis. Then our workflow matches the selfie to the Aadhaar photo, ensuring the correct person is authorizing the signature.
Video Evidence
The signer reads a short, predefined statement on camera while recording a brief video clip. This provides clear evidence of intent, free will, and consent to sign. Our AI performs multiple automated checks to help detect tampering; however, we still recommend manually reviewing the recording as an extra safety step. Video evidence is strongly recommended for high-value or high-risk documents.
Always-Valid Signatures
OTPSign signatures stay valid forever. Unlike some other providers where signatures might expire or show as invalid over time, we ensure your documents remain verifiable for years to come. All necessary verification data is securely included in the file itself, so you never have to worry about future validation issues.
Court-Ready Audit Certificate
Every signed document ships with a court-ready audit certificate. It includes signer identity, timestamps, OTP verification events, IP/device details, and cryptographic proof so you can defend the document’s integrity in any proceeding.
