Convenient and fast reading: Data reading does not require a light source, and can even be carried out through the outer packaging. The effective identification distance is greater, when the active tag with its own battery is used, the effective identification distance can reach more than 30 meters;
Fast recognition speed: As soon as the tag enters the magnetic field, the reader can read the information in it instantly, and it can process multiple tags at the same time to achieve batch recognition;
Large data capacity: The two-dimensional barcode (PDF417) with the largest data capacity can only store up to 2725 numbers; if it contains letters, the storage capacity will be less; RFID tags can be expanded to dozens of K according to user needs;
Long service life and wide range of applications: its radio communication method allows it to be used in dust, oil and other highly polluted environments and radioactive environments, and its closed packaging makes its lifespan much longer than printed bar codes;
