I. better security: it can not only be embedded or attached to products of different shapes and types, but also set password protection for reading and writing of label data，So it has higher security;

2. Tag data can be changed dynamically: the programmer can write data to, thus giving RFID tags the function of interactive portable data file, and writeLess entry time than barcode printing;

3. Dynamic real-time communication: the tag communicates with the reader at a frequency of 50-100 times per second, so as long as the object attached to the RFID tag appears in theWithin the effective recognition range of the interpreter, its position can be dynamically tracked and monitored;

IV. fast recognition speed: as soon as the tag enters the magnetic field, the reader can read the information in it immediately, and can process multiple tags at the same time, realizing batchDistinguish;

V. large data capacity: the two-dimensional barcode with the largest data capacity can only store 2725 numbers at most; if it contains letters, the storage capacity will be less; RFIDTags can be expanded to tens of K according to users' needs

Vi. long service life and wide application range: its radio communication mode enables it to be used in dust, oil pollution and other highly polluted and radioactive environment, andIts closed packaging makes its life much longer than the printed bar code;

7. Easy and fast reading: the data can be read without light source or even through the outer package. The effective recognition distance is larger, and the initiative of self-contained battery is adoptedWhen labeling, the effective recognition distance can be more than 30 meters.
