- the connecting end 23 is used for connecting with a radio frequency identification chip (hereinafter referred to as an RFID chip, not shown in the figure).
- the RFID chip is arranged on the main board to provide radio frequency signals or process the received electromagnetic wave signals.
- the RFID chip can be directly connected to the connection terminal 23, or can be connected to the connection terminal 23 through a structure such as a metal shrapnel.
- the face recognition device 100 provided by the embodiment of the present disclosure is connected to the RFID chip by extending the extension 22 to the other surface of the center plate 11, so that there is only the main body between the center plate 11 and the opposite surface of the metal plate 31. Part 21 without redundant components; in this way, it is easy to set the installation structure and the connection structure with the screen assembly 30.
- the RFID antenna 20 is a flexible circuit board.
- the flexible circuit board has the characteristics of ultra-thin structure and easy manufacture; making the RFID antenna 20 into a flexible circuit board can reduce the thickness of the face recognition device 100.
- the face recognition device 100 can realize the face recognition function; here, the face recognition device 100 further includes a camera, a processor, and a memory, and a camera hole is also opened on the screen assembly 30 (refer to FIG. 1 The function hole 301), the camera collects the user's face image through the camera hole, the processor recognizes the user's face image, and matches the recognition result with the user information stored in the memory to identify the user's identity and realize the face recognition function. In this way, on the basis of realizing the face recognition function, the face recognition device 100 can also perform RFID card swiping, which can realize double identity verification and improve security.
- the face recognition device 100 of the embodiment of the present disclosure includes any one of the following: a face recognition machine, a face recognition gate integrated machine, a face recognition and identity authentication integrated machine, a building intercom, an access control machine, etc., which can realize a face Recognition and RFID card swipe dual identity authentication, high security.
- the radio frequency antenna is arranged between the middle frame and the screen assembly, and the screen assembly is provided with a clearance area, the radio frequency antenna can radiate electromagnetic waves through the clearance area on the screen assembly, thereby being able to interact with the electronics.
- the tag establishes communication; therefore, the face recognition device of the present disclosure can realize the card swiping function without increasing the volume of the face recognition device.
