RFID technology is ubiquitous in life, such as hotel access cards, university canteen meal cards, and even second-generation ID cards all use RFID technology.
RFID is the abbreviation of Radio Frequency Identification, which is called radio frequency identification technology in Chinese. It is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals, without manual intervention.
RFID consists of three parts: tag, reader and antenna.
Labels: composed of coupling components and chips, each label has a unique electronic code, and high-capacity electronic labels have a user write area, which is attached to the object to identify the target object.
Reader writer: device for reading and writing tag information
Antenna: transmit RF signal between tag and reader writer
Features of RFID tag:
1. Fast wireless identification scanning, which can read multiple labels at the same time
2. It is small in size, and can be pasted at an appropriate location or hung at a certain location, with various appearances and shapes.
3. Anti pollution, durable, high and low temperature resistant, special labels can be waterproof, dustproof and metal resistant.
4. There are tamper proof, disposable and reusable types. RFID tags can store permanent and non permanent data
5. The signal has good penetrability, and can pass through similar non-metallic materials (such as paper packaging boxes, plastic shells, etc.), and can be read (read and write) without barriers in the gas space.
6. Large storage space and information memory capacity. The storage capacity of RFID tags is more than 94th power of 2 (nearly 10000 words)
7. High security, multiple encryption measures during signal transmission, data security, and only RFID tags in the system are allowed to be read and written.
8. RFID tags have excellent physical performance and can be packaged in paper media
9. Multiple encryption, with the world's unique ID number, to ensure security
10. RFID tag identification technology is advanced, and automatic identification is accurate through computer network and data processing technology
11. It can be identified by hand-held reader (PDA) or fixed RFID reader without error
12. The system can be based on Windows or Android platform, Chinese interface, simple operation, installation and debugging, easy maintenance, stable and reliable.
13. RFID tag radio frequency identification can improve the efficiency of goods management, quickly identify, simplify management, set permissions, easily expand, realize statistics, query, tracking and other functions, and remotely communicate with other places for identification, remote query and other functions.
14. Product information can also be obtained offline
