Advantages of RFID Cards.


RFID technology has advantages such as long service life, wide application range, good security and so on.

RFID chips and RFID readers are highly resistant to substances such as water, oil, and chemicals. The reading of information is not limited by the size and shape of the chip. It does not need to match the fixed size and printing quality of the paper for reading accuracy. Moreover, RFID tags are developing in miniaturization and various forms to be applied to different products. .

 Compared with traditional smart chips, RFID technology identification is more accurate, and the identification distance is more flexible. Penetration and barrier-free reading can be achieved. The RFID chip tag can repeatedly add, modify, and delete the data stored in the internal storage to facilitate the update of information. The content of the internal data is protected by a password, so that the content is not easy to be forged and altered. The data capacity of RFID chips is very large, and with the development of technology, the capacity is still increasing.

In addition, the advantage of RFID technology is that data reading does not require a light source, and can even be carried out through the outer packaging. The effective identification distance is larger. When the active tag with its own battery is used, the effective identification distance can reach more than 30 meters; 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 to realize batch processing. 

Recognition; 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 the needs of users; using the programmer Data can be written to the tag, thus giving the RFID tag the function of an interactive portable data file, and the writing time is less than that of printing a barcode; the tag communicates with the reader at a frequency of 50 to 100 times per second, so as long as the RFID The object attached to the tag appears within the effective recognition range of the reader, and its position can be dynamically tracked and monitored.
