As shown in Figure 1, the barcode scanning contracting method of the present embodiment includes:
Step S1 receives the contract documents of upload and the identity information of each contract party.Specifically, it can be obtained by log-on message
The identity information for taking each contract party, after each side appoints, wherein a side uploads contract documents, remaining each side need to only be logged in,
Usually by signing initiator (such as: label labour contract when employing unit) upload contract documents.
Step S2 respectively verifies the identity information of each contract party, and the identity to ensure each contract party is authentic and valid.
Verification mode includes but is not limited to short-message verification, mailbox verifying, bank card factor authentication, U-shield authenticate, recognition of face authenticates, when
So each contract party needs to register in advance with corresponding true identity information.
Step S3, after being verified, based on contract the identity information of file, initiation signing time and each contract party is generated only
One condition code.Initiate signing the time be receive upload contract documents time, unique features code be the secondary signing only
One mark.
Step S4 generates two dimensional code according to the unique features code and the identity information of each contract party, and two dimensional code is pushed away
It send to user terminal (user terminal of each contract party).
Step S5 generates the sign-up page including signing information after user terminal identifies two dimensional code, and pushes to user
Terminal receives each contract party and operates in the signing of user terminal to complete to contract, and the signing information includes: contract documents, each
Contract party's identity information initiates signing time and unique features code.
Each contract party scans the two-dimensional code opening signing web page in user terminal, writes the label of oneself on the subscriber terminal
Name, clicks and drags to and formulate position, and finally clicking completing button terminates to contract, and expression is contracted successfully.
Step S6 generates CA certificate according to the signing information, and the CA certificate is covered onto contract documents.
The barcode scanning of the present embodiment is contracted, and is made user's signing more convenient, is made concluding parties more intuitive and convenient, may be implemented
Strange land signing, saves and uses paper, contracts at low cost.
