RFID Advantage

- Jan 24, 2019-

RFID is a flexible application technology that is easy to handle, simple and practical, and especially suitable for automated control. Can work freely in a variety of harsh environments: short-range RF products are not afraid of oil, dust pollution and other harsh environments, can replace bar codes, such as used in the factory line to track objects; long-range RF products are used for transportation, identification distance can be Up to tens of meters, such as automatic charging or identification of vehicle identity. Radio frequency identification systems have the following system advantages:

Easy to read: Data is read without a light source, or even through an outer package. The effective recognition distance is larger, and when the active label with the battery is used, the effective recognition distance can reach more than 30 meters;

Fast recognition speed: When the tag 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 identification;

Large data capacity: the largest data volume of the two-dimensional barcode (PDF417), can only store up to 2725 numbers; if it contains letters, the storage will be less; RFID tags can be expanded to 10K according to user needs;

Long service life and wide application range: its radio communication method can be applied to high-pollution environment and radioactive environment such as dust and oil, and its closed packaging makes its lifespan greatly exceed the printed bar code;

Tag data can be dynamically changed: the programmer can write data to the tag, giving the RFID tag the ability to interactively load portable data files with less write time than printed bar codes;

Better security: not only can be embedded or attached to different shapes and types of products, but also can be password protected for reading and writing of tag data, thus providing higher security;

Dynamic real-time communication: the tag communicates with the reader at a frequency of 50 to 100 times per second, so that 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.
