[0002] In elevator scenarios, due to security needs, a pass verification device is usually set up. The most common one is to use an RFID identification reader as a card swipe for pass verification.

[0003] Since elevators are used very frequently and for a long time, the RFID identification readers used in ordinary elevator scenarios have the following technical disadvantages: (1) Traditional RFID card readers are mostly plastic shells, which are prone to aging and corrosion after long-term use in elevator scenarios, resulting in a limited service life; (2) Traditional RFID card readers need to be kept close when in use, and sometimes the card swiping is not sensitive; (3) Traditional RFID card readers are relatively thick and the workmanship is not beautiful. In elevator scenarios, the thick structure is not convenient to use. Therefore, the present technical solution proposes an RFID identification reader for elevators. Utility Model Content

The RFID antenna board is embedded between the circular outer frame and the front panel, and is light and thin in size and light in structure. The front panel adopts a film or glass structure and can completely cover the RFID antenna board, so that it can not only be firmly attached to the RFID antenna board but also does not affect the signal emitted by the RFID antenna board, and has high sensitivity. The wave-absorbing electromagnetic film arranged at the rear of the RFID antenna board can effectively isolate the signal between the metal and the antenna, and improve the problem of insensitive card swiping. The back of the circular outer frame is provided with a nano double-sided adhesive with a reserved hole for antenna threading, which has high viscosity and is easy to use.
