Radio Frequency Identification(RFID),also known as Radio Frequency Identification(RFID)technology,is a type of automatic identification technology that uses wireless radio frequency for non-contact bidirectional data communication.It uses wireless radio frequency to read and write recording media(electronic tags or RF cards)to achieve identification goals and data exchange.It is considered one of the potential information technologies of the 21st century.

　　Wireless radio frequency identification technology achieves the purpose of identification by combining wireless communication with data access technology through contactless rapid information exchange and storage technology,and then connecting to a database system to achieve contactless bidirectional communication.It is used for data exchange and connects an extremely complex system.

　　In the recognition system,electronic tags are read,written,and communicated through electromagnetic waves.According to the communication distance,it can be divided into near field and far field.Therefore,the data exchange mode between the read/write device and the electronic tag is also correspondingly divided into load modulation and backscatter modulation.

　　RFID reagent cabinets are mainly launched for industries such as healthcare,education,chemistry,and chemical engineering that require the management of regulated hazardous chemicals.RFID technology effectively solves the drawbacks of traditional operations,enabling 24-hour unmanned operation.Users can access chemical reagents at any time and the system can automatically record them.Unauthorized individuals cannot touch chemical/medical reagents,preventing unauthorized claims and irregular operations.Managers can remotely authorize and understand the use of hazardous chemicals in real-time.

　　The intelligent reagent management cabinet allows for real-time understanding of the usage status of controlled reagents and relevant user information.The weighing system of the intelligent reagent management cabinet can also obtain chemical weight information,and integrates multiple sensors internally to ensure the stable operation of the entire system.
