In recent years, the educational administration management system platform has been basically used in the education and training market. When members sign in for class, most of them swipe their cards and print the sign-in receipt on the thermal paper receipt machine. The above-mentioned different types of sticker wholesale manufacturers produce similar sign-in thermal paper receipt machines, most of which need to load thermal paper in advance, and then connect to the host through a data cable or Bluetooth. When a member prints a class ticket, the center staff operates the computer to print the class ticket at the same time.
As the above-mentioned existing receipt printer needs to be associated with the computer host, operating software, membership card check-in machine and other equipment, although to a certain extent to achieve the purpose of signing in for class members, but also need the assistance of computer staff to complete, making the existingSticker wholesale manufacturersThe small ticket printing device cannot fully realize self-service operation, and the operation efficiency is low.
Based on the above purpose, the method, device, equipment and system for printing check-in business cards provided by the sticker wholesale manufacturer include the following steps: judging whether to scan the encrypted two-dimensional code in real time; The encrypted two-dimensional code is obtained by receiving the card number and password of the membership card, obtaining the corresponding member category information according to the card number and password of the membership card, and then calling the symmetric algorithm to encrypt the member category information using the preset private key; member class information includes membership card number, member name and class time; When it is determined that the encrypted two-dimensional code needs to be scanned, scan and read the currently received encrypted two-dimensional code; Call the symmetric algorithm to decrypt the encrypted two-dimensional code through the public key corresponding to the private key, and identify whether the decrypted encrypted two-dimensional code is correct; If the decrypted encrypted two-dimensional code is identified as correct, the corresponding member category information in the encrypted two-dimensional code is obtained; if the decrypted encrypted two-dimensional code is identified as incorrect, return to the step of continuing to determine whether to scan the encrypted two-dimensional code in real time; After obtaining the member category information, display the member category information; Wait for receiving the printing instruction of the member category information, after receiving the printing instruction, print the sign-in of the member category information according to the printing instructionSticker wholesale manufacturersBusiness cards; where, printedSticker wholesale manufacturersThe sign-in post is printed with member category information; When it is judged that the encrypted two-dimensional code does not need to be scanned, it enters the sleep state and displays and plays the pre-stored built-in picture.

The above invention obtains the corresponding member category information by scanning the pre-generated encrypted two-dimensional code containing the member category information, decrypts and identifies the pre-generated encrypted two-dimensional code, and then displays the corresponding member category information. It can be operated by members alone without the assistance of staff, which realizes the purpose of self-service printing of sign-in name posts.
