Characteristics and advantages of RFID technology

RFID is an application technology that is easy to operate, simple and practical, and particularly suitable for flexible automation control. Identification work does not require manual intervention. It can support both read-only and read-write working modes without the need for contact or aiming; Can work freely in various harsh environments: Short distance RF products are not afraid of oil stains, dust pollution and other harsh environments, and can replace barcodes, such as tracking objects on factory assembly lines; Long range radio frequency products are often used in transportation, with recognition distances of up to tens of meters, such as automatic toll collection or vehicle identification. Its unique superiority is unmatched by other recognition technologies. There are mainly the following aspects:

Easy and fast reading: Data reading does not require a light source and can even be done through the outer packaging. The effective recognition distance is longer, and when using active tags with built-in batteries, the effective recognition distance can reach more than 30 meters;

Fast recognition speed: As soon as the tag enters the magnetic field, the reader can instantly read the information inside, and can process multiple tags simultaneously, achieving batch recognition;

Large data capacity: The two-dimensional barcode (pdf417) with the largest data capacity can only store up to 2725 digits; If it contains letters, the storage capacity will be less; RFID tags can be expanded to tens of thousands according to user needs;

Long service life and wide application range: Its wireless communication method makes it suitable for high pollution and radioactive environments such as dust and oil pollution, and its closed packaging greatly extends its lifespan beyond printed barcodes;

Tag data can be dynamically changed: using a programmer, data can be written into electronic tags, giving RFID tags the function of interactive and portable data files, and the writing time is shorter than printing barcodes;

Better security: RFID electronic tags can not only be embedded or attached to products of different shapes and types, but also set password protection for the reading and writing of tag data, thus having 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.
