Radio Frequency Reader

Part of radio frequency identification(RFID)

1. Electronic tags

Electronic tags are RFID tags, some of which are called radio frequency tags and radio frequency identification. It is a kind of non-contact automatic identification technology, which can identify the target object and obtain relevant data through radio frequency signals, without manual intervention. As a wireless version of bar code, RFID technology has many advantages, such as waterproofness, antimagnetic, high-temperature resistance, long service life, long reading distance, encryption of data on the tag, the larger capacity of stored data, and free change of stored information, which bar code does not have.

2. RFID reader

Radio frequency identification technology, is usually used for wireless transmission and reception. Is the abbreviation of Radio Frequency Identification (RFID),

3. RFID antenna

Transmitting radio frequency signals between the tag and the reader.

RFID system principle

The system consists of an RFID tag and an RFID reader-writer. An RFID tag consists of an IC chip and microstrip antenna. The microstrip antenna gets energy from the radio waves emitted by the RFID antenna connected to the RFID reader-writer. After the IC chip gets power, it can encode the ID number or data storage area information stored in the chip and send it out through the microstrip antenna. After the RFID reader-writer receives and decodes the information through the antenna, it can get the ID number or data area content of the RFID tag, and the process of writing data is similar.
