The initiator adds the signer(s) by entering their email ID and phone number and uploads the paper to Certinal. The signer's email ID receives a request to sign the paper. After carefully reading the document, the signer agrees to sign it. The system then produces an OTP and sends it to the signer's phone number and email address. The electronic signature is formed on the document after inputting the OTP. The signed document also receives an audit trail and a Certificate of Signature Completion.
