Sign with verified identity
Every signer is recorded and verified before signing. Legally binding, you know exactly who signed, when, and that they accepted willingly. Included in Lease Agreement and Legal Policy.
Four verification layers that shield every signature
Every signature goes through a verification process no in-person signing can match. Fraud and identity theft prevention at every step.
Video-signature with proof of life
The person is recorded while signing. Their handwritten signature and a proof of life are captured, ruling out deepfakes, pre-recorded videos, or AI impersonation.

Video agreement acceptance
The signer is recorded accepting the contract terms. A real-time selfie is captured to link their face to the agreement.

Facial biometric comparison
The face on the official ID is compared with the live person. If they don't match, the signature is blocked. The ultimate protection against identity theft.
