However, at the same time, due to the restriction that clocking in through mobile phones requires unobstructed network to complete the clocking in, it has brought many problems. When users are in places without network coverage, such as underground garages and places with weak signals in the wild, they cannot perform clocking in, which causes inconvenience.

[0003] Chinese patent CN106485803A discloses an offline clock-in method, including: obtaining terminal network information; the terminal determines whether the network condition is in an abnormal condition; when the network condition is in an abnormal condition, the clock-in data input by the user is saved in the first storage area to obtain a clock-in data file; when the network condition is in a normal condition, the clock-in data file in the first storage area is sent to the server, so that the server uses the clock-in data file in the first storage area to complete the clock-in operation for the corresponding user. In summary, when the user of this application performs the clock-in operation, there is no need to maintain a good network connection or an online state. As long as the network connection can be restored later and the local clock-in data is uploaded to the server, the clock-in operation can be completed, avoiding the clock-in failure caused by the user being unable to connect to the network when clocking in due to various reasons, and reducing the dependence on the real-time network. In addition, the application also discloses an offline clock-in terminal, server and system accordingly.

The download module of the PU client downloads the registration information and punch-in rules of the participants, and logs in to the PU client using the administrator IC card; S3: The administrator brings the PU client to the event site, selects the corresponding event check-in point, chooses to check in, check out, or check in during the process, and performs normal or abnormal check-in; Normal check-in steps: The QR code reading unit is used to read the participant's registration QR code, and the time acquisition unit simultaneously obtains the time information when the QR code reading unit scans the code. The comparison unit compares the information of the QR code reading unit and the time acquisition unit with the settings in the registration information storage unit and the punch-in rule storage unit at the same time to obtain whether the punch-in is successful or failed, and the local information storage unit stores the successful punch-in record; Abnormal check-in steps: If the participant does not bring the successful registration QR code, the participant provides the administrator with his / her name, ID number or phone number. The administrator searches for the successful registration QR code of the participant in the registration information storage unit through the search module and pushes the QR code to the QR code reading unit. The QR code reading unit reads the participant's registration QR code. The time acquisition unit simultaneously acquires the time information when the QR code reading unit scans the code. The comparison unit compares the information of the QR code reading unit and the time acquisition unit with the settings in the registration information storage unit and the punch-in rule storage unit to obtain whether the punch-in is successful or failed. The local information storage unit stores the successful punch-in record and requires the participant to leave a signature. After the abnormal punch-in unit takes a photo, the photo is stored in the local information storage unit. S4: After the event, the check-in screening module screens the check-in and check-out records of the participants as well as the punch-in records during the event, and removes the punch-in records of the participants with incomplete punch-in records, retains the information of the participants with complete punch-in records, and uploads it to the platform management server to complete the event punch-in; S5: The platform management server receives the abnormal clock-in record and sends a receipt to the user terminal. The participant uploads his or her signature through the identity confirmation module. The platform management server compares the notes and finally confirms whether the clock-in is valid.

9. A clocking-in method for an offline clocking-in system for event site check-in as claimed in claim 8, characterized in that: The S1 comprises the following steps: S11: Participants log in to the platform management server through user terminals, sign up for relevant activities, fill in relevant registration information, and the database records and saves it; S12: After the registration is successful, the permission acquisition module obtains the album management permission of the user terminal through the user's consent, the platform management server generates a QR code indicating the participant's successful registration and sends it to the user terminal, and the QR code saving module automatically saves the QR code indicating the successful registration to the album; S13: When participating in the event, the user arrives at the event site with a user terminal that has saved the successful registration QR code.
