RFID is radio frequency identification, and RFID (radio frequency identification) technology, also known as radio frequency identification, is a communication technology. It can identify a specific target and read and write related data through radio signals, without establishing a mechanical or optical connection between the identification system and the specific target.
Accordingly, the target that can be RFID is called RFID tag. The most common tag is an electronic chip that records some information. This kind of chip is used in China's second-generation resident ID card. Some access control systems and bus cards have adopted this chip and identification system.
RFID printer is a device that can print the contents of the designated part of the chip (RFID tag) on the visual (paper) label after RFID identification.
