What is RFID?
RFID, full name of Radio frequency identification. It is a technical means to identify by radio frequency, such as bus cards, e-passports, bank cards, credit cards, access cards, etc, which are used by people in daily life. Its function is the same as that of common barcode labels.
The difference between RFID and QR code or barcode is that RFID does not need to be aligned, does not need light, and only needs to be touched.
If there is an RFID tag on the product, it needs to be read by RFID identification equipment. After reading and parsing, it is transferred to the system for further operation after system identification.
