The rapid development of RFID technology makes it more advanced than other technologies. SHANGHAI STAR introduces the seven advantages of RFID cards.
① Easy and fast to read
No light source is needed to read the data, and it can even be carried out through the outer packaging. The effective identification distance is greater. When using an active label with its own battery, the effective identification distance can reach more than 30 meters.
② Large data capacity
The two-dimensional barcode with the largest data capacity (PDF417) can only store up to 2,725 digits; if it contains letters, the storage capacity will be less; RFID tags can be expanded to 10K according to the needs of users.
③ Tag data can be changed dynamically
The programmer can be used to write data to the tag, giving the RFID tag the function of an interactive portable data file, and the writing time is less than printing a barcode.
④ Better security
Not only can it be embedded or attached to products of different shapes and types, but also password protection can be set for the reading and writing of tag data, thus having higher security.
⑤ Fast recognition speed
As soon as the tag enters the magnetic field, the reader can immediately read the information in it, and it can simultaneously process multiple tags to achieve batch identification.
⑥ Long service life and wide application range
Its radio communication mode makes it applicable to highly polluted and radioactive environments such as dust and oil pollution, and its closed packaging makes its lifespan greatly exceed the printed bar code.
⑦ 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 recognition range of the reader, its position can be dynamically tracked and monitored.
