In some units that require management of archives, files, and confidential documents (such as government, military, large and medium-sized enterprises, hospitals, schools, libraries, and classified agencies), RFID technology is introduced to paste RFID light tags on each archive, and record archive information through RFID card issuers and associate them one by one. This not only solves the problems of rapid inventory, borrowing and returning management, and permission management of archives, but also solves the problem of "how to accurately find the desired archives in dense archives". When it is necessary to borrow or return archives, Chainway C72 UHF RFID handheld reader sends a lighting command to light up the corresponding RFID tag of the required archive, which can quickly locate the corresponding archive, make it clear and visible, and greatly improve the efficiency of archive search.
