RFID tag is a passive or active device, which carries unique identification information and communicates by receiving radio waves emitted by readers. RFID tags can be attached to items, such as goods, vehicles, animals, etc. It can exist in various forms, such as cards, stickers, labels or embedded items.
An RFID reader is a device used to communicate with RFID tags. When the reader emits radio waves, the RFID tag will respond and transmit its own information after receiving the signal. The reader can read, write or perform other operations to realize the identification, tracking and data management of the items attached to the RFID tag.
RFID technology has the following characteristics and advantages:
1. contactless communication: RFID tags and readers can transmit and identify data without physical contact.
2. Rapid identification: RFID technology can quickly identify a large number of items in a very short time.
3. Mass storage: RFID tags have a large memory capacity and can store more data.
4. Long-distance reading: RFID technology can realize long-distance data reading and communication.
5. Good anti-interference: RFID technology has strong anti-interference ability and can realize stable data transmission in complex environment.
RFID technology is widely used in logistics, retail, manufacturing, medical care, warehousing, agriculture and other fields, and has achieved many purposes such as item traceability, inventory management, product authentication, identity recognition and so on.
