RFID technology is so great, what are its core and advantages?


Latest company news about RFID technology is so great, what are its core and advantages?



Chip is undoubtedly one of the core technologies in most electronic information products.

RFID chips are divided into tag chips and reader chips. Taking the label chip as an example, it integrates all circuits except the label antenna and matching line, including modules such as the RF front end, the analog front end, the digital baseband and the memory unit. The basic requirements for the chip are light, thin, small, high stability and low price.


In China, local manufacturers have also been able to research and develop their own low-frequency and high-frequency chips, and have achieved certain results in small size and low power consumption, and the price is about 30% more than the price advantage of foreign manufacturers.


It is understood that the current domestic independent research and development, and has been put into production of RFID chip manufacturers in Shanghai Fudan Microelectronics, Yuanwang Valley, Juchen semiconductor and so on.


The development trend of RFID chip design and manufacturing technology will continue to be lower power consumption, longer distance, faster read and write speed, higher reliability and security, and continuous cost reduction. For domestic RFID chip manufacturers, the most important thing is stability, including the production process still needs to be improved.



As the carrier of signal transmission, the importance of antenna is self-evident. Antennas are also divided into label antennas and reader antennas.


Depending on the application, RFID tags may need to be affixed to different types of objects with different shapes, or even embedded inside the object. In addition, tag antenna and reader antenna also assume the role of receiving energy and transmitting energy respectively, which puts forward strict requirements for antenna design.


The goal of the antenna is to transmit maximum energy in and out of the tag chip. This requires careful design of the match between the antenna and the free space and the tag chip to which it is attached. Assuming it is used in retail goods, if the frequency bands are 435MHz, 2.45GHz and 5.8GHz,


Then the antenna must be: the volume is small enough to be able to attach to the item; Directivity with omnidirectional or hemispherical coverage; Provides the maximum possible signal to the tag chip; No matter what the direction of the item, the polarization of the antenna can match the inquiry signal of the reader; It is robust;


With the above requirements, the cost should be low enough.


Shenzhen Bowei 15 years focus on RFID antenna and label research and development, production and sales, is a national high-tech enterprises. With the strategic idea of "demand-guided application, application-driven products", Bowei intelligent integrates technological innovation into RFID products at the first time. With the concept of "Internet of Things, innovation", supported by professional team and project design experience, Bowei provides customers with overall RFID (field) solutions including antenna and tag design.


Six advantages of RFID technology


1, no visual, batch reading, a large number of RFID tags can be read by the reader at the same time, fast, batch, hundreds or even thousands of tags can be read at a time. It can also recognize high-speed, moving objects, such as trains, buses, etc.


2, high capacity, electronic labels can store more information, such as production date, storage date, etc., can also be repeatedly rewritten and reused. The data after reading is also immediately uploaded to the system for processing, and the product can be traced to the source.


3, the reading distance is far, according to the power of the reader and the gain rate of the antenna, the reading distance can range from tens of centimeters to several meters;


4, global uniqueness, can not be copied, each RFID tag is unique, in the production of the tag process, it has been bound to the label and commodity information, so in the subsequent circulation of goods, the use of the tag is the only representative of the corresponding product.


5, long storage cycle RFID tags have the characteristics of waterproof, anti-magnetic, anti-corrosion and high temperature resistance. Such as the laundry industry, animal feeding industry, medical industry, etc., have higher requirements for label durability. At present, the general label storage time can reach several years, ten years or even decades.


6, one of the core technologies of high-security RFID tags is the chip, as we all know the difficulty of chip development, the cost is high. For counterfeiters, copying is too expensive and difficult to break through technical barriers. In addition, the electronic tag has a reliable security encryption mechanism, and the second generation of resident ID cards in China also uses RFID technology.


As one of the key technologies of the Internet of things, RFID has received more and more attention in recent years, and enterprises for the control of goods management and labor costs, RFID will also be widely used in all walks of life. As the world's manufacturing base, China already has the world's largest RFID application market, I believe that in the future in the government to promote, unified standards and cost gradually decline, with the unmanned retail new air port application, will bring RFID a high-speed growth opportunity.
