Servo motor movement from QR Code validation of the Maix-BIT board

This project works as follows: the user scans a predefined qr code and is directed to a conversation via whatsapp, after the dialogue the attendant sends the user a QR code image. The user goes to an acrylic box where the Maxi-BIT camera is positioned, it processes the qr code and validates it in a cloud application, the same one in which the attendant registered the qr code, if the qr is valid , then a servo activates the opening mechanism of the box giving access for the user to remove an item. I need the application programming where the attendant will register the qr code and the Maxi-BIT programming to process and validate the qr code, in addition to activating the servo.
