Fixed Rfid Reader Writer are generally equipped with 1-8 antenna ports, and the number of antennas depends on the coverage required by the RFID application. Some applications, such as file input and output, require only a small coverage area, so one antenna can do the job well. Other applications with larger coverage areas usually require multiple antennas to create the necessary coverage. The fixed Rfid Reader Writer only needs to be fixed in a certain place and kept powered on, and it will continue to collect data. Therefore, if you want to collect how many goods are in the warehouse in a d

With the continuous development of society, RFID tags have developed rapidly in all walks of life. Nowadays, the market is getting bigger and bigger. Many people can't distinguish the difference between RFID tags and NFC tags. Today, Shenzhen smart manufacturers will share with you:     NFC tags are developed on the basis of RFID tags. In essence, NFC is not much different from RFID, and is based on the signal transmission between two objects with similar geographic locations.  However, there is still a difference between NFC and RFID. NFC technology adds a point-to-po

What are the packaging forms of RFID electronic tags? In fact, there are many packaging forms of RFID electronic tags, and they are not restricted by size and standard shape. Their composition is also very different. Different packages are used mainly according to the different characteristics of the application and the use environment. form. Generally, there are three categories that can be seen in the application cases. Among them, the package of the heterogeneous type is even more varied. Packaging form of rfid electronic tag: 　　1, cards (PVC, paper, other) 　Laminated type: There are

Electronic tags (Tag): composed of coupling elements and chips, each RFID tag has a unique electronic code, attached to the object to identify the target object, commonly known as electronic tag or smart tag rfid electronic tag: active tag, passive tag, semi Active semi-passive tags. RFID working principle: After the tag enters the magnetic field, it receives the radio frequency signal from the reader, and uses the energy obtained by the induced current to send out the product information stored in the chip (Passive Tag, passive tag or passive tag), or actively send a certain Frequency

RFID tags are composed of tags, readers, and data transmission and processing systems. -Generally divided into active RFID, semi-active and passive RFID, the chip with antenna is stored in the chip, and the information that can identify the target is stored in the chip, and the main function is to identify the goods.    So, how do RFID tags distinguish between active, semi-active and passive? 1. Different concepts     Active RFID, also known as active RFID (Active tag), is usually used to track high-value items at a long distance. Compared with passive RFID, it can t
