What Are The Characteristics Of RFID Systems?

With the continuous maturity of RFID technology and the increasing number of cross regional and cross industry applications, the advantages of RFID systems have gradually been proven and become a popular application technology. What are the characteristics of RFID systems?

Read/write performance of non-contact data
RFID can directly read information into the database in a non-contact operation state, and can process multiple tags at once. The processing status can be written into the tags for the next stage of processing and reading judgment. The reading and writing distance of the tag ranges from a few centimeters to several tens of meters, making it suitable for relatively short distance wireless transmission of information.

Reliability and durability
There is no mechanical contact between the RFID tag and the reader, avoiding reading and writing errors caused by poor contact. Even in harsh external environments, it does not affect reading and writing. In addition, RFID chips are packaged inside, so there is no need to worry about chip detachment, electrostatic breakdown, bending damage, etc., so the service life is relatively long.

Fast and convenient
RFID can recognize and read multiple RFID tags simultaneously, greatly improving work efficiency. Due to the use of non-contact communication, the reader can operate RFID tagged identification objects within a range of a few centimeters to tens of meters, so there is no need to perform insertion and removal work like IC cards. When in non-contact use, there is no directionality, which can greatly improve the speed of use and complete read and write operations in a very short time.

Large data memory capacity
The capacity of a one-dimensional barcode is 50B, the maximum capacity of a two-dimensional barcode can store 1108B, and the maximum capacity of an RFID is several megabytes. With the development of memory carriers, there is also a trend of continuous expansion of data capacity. The amount of information required for future items to carry will continue to increase, and the demand for expanding the capacity of labels will also correspondingly increase. There are multiple partitions in RF, each with its own password, so different partitions can be used for different applications to achieve versatility.

Anti collision mechanism
RFID tags have a fast anti-collision mechanism that can prevent data interference between tags. Therefore, the reader can process multiple non-contact tags simultaneously, and can process multiple tags simultaneously.

Security
Due to the electronic nature of information carried by RFID, its data content can be password protected, making it less susceptible to forgery and alteration. The serial number of RFID tags has uniqueness, and the manufacturer has solidified this serial number before the product leaves the factory and cannot change it again. The reader can verify the legitimacy of the tag, and the tag can also verify the legitimacy of the reader. Before processing, the card needs to authenticate with the reader, and all data is encrypted during the communication process. In addition, each part of the RFID tag has its own operation password and access conditions.

Smaller size and more diverse shapes
RFID tags are not limited by size or shape in reading, and do not need to be matched with fixed paper size and printing quality for reading accuracy. In addition, RFID tags can be developed into miniaturization and diverse forms to be applied to different products.

Penetration and barrier free reading
When covered, RFID tags can penetrate non-metallic or non-transparent materials such as paper, wood, and plastic to exchange information with readers and writers. Only iron metal, due to its shielding effect, hinders the propagation of electromagnetic waves and prevents normal communication. Therefore, RFID anti metal tags are needed to achieve information exchange in metal environments.

Flow monitoring and positioning
RFID tags can be attached to objects for detection and positioning. From raw material procurement, product production to product sales, all information about the product can be recorded using RFID tags. In case of accidents, the source of the problem can be quickly and accurately traced, achieving product quality tracking.
