Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a dining billing device based on face recognition. Background Art

[0002] In daily business work, the company often needs to call everyone to meetings. The attendees who sign in at the meeting have already participated in the reimbursement of meeting fees and meal expenses on the same day, and have already used up the meal expenses once. When dining in the cafeteria, there should be no need to swipe the card to dine. Otherwise, the attendees who sign in at the meeting will use up the meal allowance given by the company to employees again when swiping the employee card, thereby repeatedly using up the company's expenses.

[0003] However, the existing company cafeteria mainly accepts payment by swiping employee cards, and is unable to identify and distinguish temporary attendees, resulting in the restaurant subsidy amount exceeding the limit.

[0004] Existing card payment machines do not have a facial recognition function. For example, a construction site canteen payment machine disclosed in CN201720032636.3 can quickly identify personal identities and prevent fraudulent payment by setting up a card reader, RFID reader, signal interface and alarm device, but the device cannot distinguish between temporary participants and employees.

[0005] For example, CN 201821995200.5 discloses a canteen payment system based on facial recognition. The system is equipped with an ordering subsystem, a payment subsystem, an all-in-one machine and a communication unit. The payment subsystem includes a facial feature library and a billing unit. The entire payment process is completed by swiping the face, truly realizing one person one "card". Facial recognition is more efficient, accurate and convenient, and can fundamentally eliminate the occurrence of wrong swiping and multiple people using one card in traditional canteen payment methods, thereby avoiding management chaos.

[0006] However, the device cannot supplement the light of the face in combination with the use environment, resulting in the problem of low accuracy of face recognition results in the existing face recognition process due to inaccurate collection of facial features of the person to be recognized. In addition, the device deletes the card swiping function and cannot meet the dining needs of normal staff card swiping.

[0007] The information disclosed in the background technology section is only intended to increase the understanding of the overall background of the utility model, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to ordinary technicians in the field.
