According to relevant public information, the electronic certificate of the first witness is usually issued by an authoritative organization, including time stamp, digital signature and other information, which can prevent the evidence from being tampered with or forged. The certificate contains detailed information and description provided by the first witness, as well as evidence such as photos or videos on the spot, which can be used as effective evidence for court trials and insurance claims. Using the electronic certificate of the first witness can reduce the difficulty of obtaining evidence, improve the authenticity and credibility of evidence and provide strong support for solving related disputes.
