  • Publication number: 20250239105
    Abstract: The present invention relates to an on-site signature process verification system and verification method. In this system, a first camera of an intelligent signature pen obtains a first image information of the image at the signing position, and a second camera of the intelligent signature pen obtains a second image information of the signing environment image. The intelligent signature pen sends the first image information and the second image information to an intelligent mobile terminal. The intelligent mobile terminal uploads the first image information and the second image information to a cloud server. A verification terminal obtains and displays the first image information and the second image information for verification from the cloud server. The present invention uses an intelligent signature pen to achieve a full record of the signature process, which can reduce labor and hardware costs and improve business efficiency.
