What are the advantages and disadvantages of RFID tags?

一. Better security: it can not only be embedded or attached to products of different shapes and types, but also can set password protection for reading and writing label data, thus having higher security.

二、Label data can be changed dynamically: programming can be used to write data, thus giving RFID tags the function of interactive portable data file, and write > Less time to input than printing barcode.

三、Dynamic real-time communication: the tag communicates with the reader at a frequency of 50 to 100 times per second, so as long as the object attached to the RFID tag appears within the effective identification range of the reader, it can track and monitor its position dynamically.

四、Fast recognition speed: as soon as the label enters the magnetic field, the reader can read the information in real time, and can process multiple tags at the same time to realize batch recognition.

五、Large data capacity: the 2d barcode with the largest data capacity can only store 2,725 Numbers at most; If the letters are included, the storage capacity will be less and the labels can be expanded to tens of K according to the user's needs.RFID

六、Long service life and wide application range: its radio communication mode enables it to be applied in highly polluted environment such as dust, oil pollution and radioactive environment, and its closed packaging makes its life greatly exceed the printed barcode.

七、Easy and fast to read: data can be read without light source, or even through the outer package. The effective identification distance is larger. When using the active label with battery, the effective identification distance can be more than 30 meters.
