The advantages of RFID technology

2022-05-25

RFID is a flexible application technology that is easy to handle, simple and practical and especially suitable for automation control. Can work freely in various harsh environments: short-range RF products are not afraid of harsh environments such as oil stains and dust pollution, and can replace barcodes, such as tracking objects on factory lines; long-range RF products are mostly used in traffic, and the identification distance can be adjusted. Up to tens of meters, such as automatic charging or identification of vehicles. The RFID system mainly has the following system advantages:

Easy and fast reading: The reading of data does not require a light source, and can even be carried out through the outer packaging. The effective identification distance is larger. When using the active tag with its own battery, the effective identification distance can reach more than 30 meters;

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 to realize batch recognition;

Large data capacity: 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 10K according to user needs;

Long service life and wide application range: its radio communication method makes it applicable to high pollution environments and radioactive environments such as dust and oil pollution, and its closed packaging makes its service life much longer than that of printed barcodes;

Tag data can be changed dynamically: the programmer can write data to the tag, thus giving the RFID tag the function of an interactive portable data file, and the writing time is less than printing a barcode;
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, so it has higher security;

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 within the effective recognition range of the reader, its position can be dynamically tracked and monitored.
