Description

Technical Field

[0001] The utility model relates to the technical field of face-scanning payment, and more specifically, to a campus face-scanning payment device. Background Art

[0002] Face-scanning payment technology will become more intelligent and precise, using higher-resolution cameras and faster face recognition algorithms to improve recognition accuracy and speed. With the popularization of face-scanning payment, user privacy and security issues have also attracted attention. Future development trends will strengthen the protection of user data and adopt more secure and reliable encryption technology and privacy protection mechanisms to ensure that user personal information is not leaked.

[0003] Existing face-scanning payment devices are used in shopping malls, schools and other places. Some face-scanning payment devices in schools are installed in cafeterias. When students buy meals, they scan their faces through the payment screen according to the price and the money is deducted. However, the heights of students vary. Some existing face-scanning payment screens in cafeterias are fixed. When recognizing the faces of students of different heights, some students’ height factors lead to incomplete face recognition on the payment screen, which in turn leads to low efficiency of face recognition on the payment screen.

The position sensor 13 detects the height of the student. After receiving the information, the position sensor 13 transmits the information to the controller 11. The controller 11 receives the information and processes it, and supplies power to the motor 10. The forward and reverse rotation of the motor 10 drives the first rotating shaft 4 forward and reverse, so that the forward and reverse rotation of the gear 5 drives the arc-shaped tooth 7 forward and reverse, and the rotation of the arc-shaped tooth 7 drives the second rotating shaft 6 and the rotating frame 8 to rotate.
