[0002] RFID reader is also called "RFID reader", which is wireless radio frequency identification. It automatically identifies the target object and obtains relevant data through radio frequency identification signals without human intervention. It can identify high-speed moving objects and multiple RFID tags at the same time. It is quick and convenient to operate. RFID technology is used in many industries, such as logistics and warehousing management, anti-counterfeiting and traceability, industrial manufacturing, ETC, etc.

[0003] Application No. 202322272013.1 discloses a portable and foldable RFID reader / writer, including an RFID main body, and also including a containing box for accommodating and setting the RFID main body; the containing box includes a bottom box and a protective cover movably connected to the bottom box through a rotating shaft at the rear; it also includes a body support assembly and a battery assembly arranged inside the containing box; the battery assembly is attached to the bottom inner side of the bottom box; the body support assembly is located outside the battery assembly; the body support assembly includes two support blocks fixedly connected to the bottom box, a rotating shaft with two ends rotatably connected to the support blocks, a rotating rod with one end movably connected to the rotating shaft, and a body fixing plate movably connected to the other end of the rotating rod relative to the rotating shaft. In actual application, the body support assembly can be better utilized to realize the folding, unfolding and storage of the RFID main body, which is not only convenient to carry, but also can better protect the RFID main body.

[0004] The above solution has shortcomings when used. After the bottom box is separated from the protective cover, the RFID main body needs to be manually adjusted before the RFID main body can be flipped out of the bottom box, which increases the complexity of use for staff. Therefore, we propose a portable and foldable RFID reader to solve the above problem. Utility Model Content
