FingerSign

FingerSign verifies the signer at the moment of signing, captures intent, and generates transaction-level evidence — not just a visual stamp. No certificates, hardware tokens, or workflow friction in the core flow.

Built for proof, not just workflow

Traditional e-sign tools trust account possession. FingerSign binds verified identity, signer intent, and signed content into one independently verifiable evidence layer — powered by SyberKey at signing time.

• Real human verification — biometric identity confirmed when the signature is applied, not assumed from email or OTP.
• Evidence-based signature — cryptographic record linking identity, intent, and document hash.
• Independent verification — validate integrity via transaction ID or QR without trusting a single platform record.
• No certificate complexity — no user-managed keys or hardware token lifecycle in the core signing path.

How it works

1. Send — upload documents, assign recipients, define signing order.
2. Verify — signer identity verified with SyberKey at signing time.
3. Authorize — consent and intent captured and enforced server-side.
4. Secure — document hash, identity proof, and signing evidence bound together.
5. Verify anytime — anyone can validate status using transaction ID or QR.
