Conception :RFID is the abbreviation of Radio Frequency Identification, that is, radio frequency identification, commonly known as electronic tags, or smart tags. RFID is a wireless communication technology that stands for Radio Frequency Identification. An RFID tag is a small electronic device that communicates with a reader via radio waves. These tags usually contain a chip and an antenna that can store and transmit information.

Working principle :The chip in the RFID tag contains a unique identification code. When the tag is close to the reader, the reader sends an electromagnetic field to the tag. This electromagnetic field activates the chip in the tag and causes it to transmit an identification code to the reader. The reader can match this identification code with information in the database to manage and track the item.

Advantage :Firstly, RFID tags can be read and written without touching the item, which means they can scan multiple items faster. Secondly, RFID tags can store more information, including manufacturer, production date, batch number and selling price. Finally, RFID tags can be tracked and managed more easily, reducing manual errors and costs.

Application Industry ：RFID tags have been widely used in many fields, including logistics, inventory management, retail, healthcare and military. In the field of logistics and inventory management, RFID tags can be used to track the location, quantity and status of items, thereby improving logistics efficiency and accuracy. In the retail industry, RFID tags can be used to manage inventory, prevent theft and improve customer experience. In the field of healthcare, RFID tags can be used to track drugs, medical equipment and patient information, thereby improving the quality and efficiency of healthcare.
