The core and advantages of RFID technology

The huge market space for RFID is about to open up, and the key to a successful enterprise lies in whether it can firmly lock in and capture it before demand is formed. With the development of the industry, competition within the industry continues to intensify. Excellent domestic RFID companies are increasingly valuing research on the industry market, especially in-depth research on the industry development environment and product buyers. So what are the core and advantages of RFID technology?

RFID technology chip

Chips undoubtedly bear the brunt as one of the core technologies in most electronic information products. RFID chips are divided into tag chips and reader/writer chips. Taking tag chips as an example, they integrate all circuits except for tag antennas and matching lines, including RF front-end, analog front-end, digital baseband, and memory unit modules. The basic requirements for chips are lightweight, thin, small, high stability, and low price. The development trend of RFID chip design and manufacturing technology will still be lower power consumption, longer distances, faster read and write speeds, higher reliability and security, and continuous cost reduction. For domestic RFID chip manufacturers, the most important thing is stability, including the need for further improvement in production processes.

 RFID technology antenna

As a carrier of signal transmission, the importance of antennas is self-evident. Antennas are also divided into tag antennas and reader/writer antennas. According to the different application scenarios, RFID tags may need to be affixed to objects of different types and shapes, or even embedded inside the objects. In addition, the tag antenna and the reader antenna also bear the roles of receiving energy and transmitting energy respectively, which pose strict requirements for antenna design. The goal of the antenna is to transmit the maximum amount of energy into and out of the tag chip. This requires careful design of the antenna and free space, as well as the matching of their connected tag chips.
So RFID technology antennas must be small enough to stick to objects; Directionality with omnidirectional or hemispherical coverage; Provide the maximum possible signal to the chip of the tag; Regardless of the direction of the object, the polarization of the antenna can match the inquiry signal of the reader; Has robustness; Having the above requirements, ultimately, the cost should be sufficiently low.

The Six Advantages of RFID Technology

1. No need for visual or batch reading, a large number of RFID tags can be read and written by readers simultaneously, quickly, and in batches. Hundreds or even thousands of tags can be read at once. It can also recognize high-speed and moving objects, such as trains, buses, etc.
2. High capacity, electronic tags can store more information, such as production date, storage date, etc., and can also be repeatedly rewritten and reused. The read data is also instantly uploaded to the system for processing, and it can also achieve traceability of the product.
3. The reading distance can range from tens of centimeters to several meters depending on the power of the reader and the gain rate of the antenna;
4. Global uniqueness and non replicability. Each RFID tag is unique, and during the production process, the tag is already bound to the product information. Therefore, in the subsequent circulation and use of the product, this tag is the only representative of the corresponding item.
5. Long storage cycle
RFID tags have the characteristics of being waterproof, anti magnetic, corrosion-resistant, and heat-resistant. The laundry industry, animal husbandry industry, medical industry, etc. all have high requirements for the durability of labels. Currently, the average label retention time can reach several years, tens of years, or even decades.
6. High security
One of the core technologies of RFID tags is chips, which are well-known for their high difficulty and cost in development. For counterfeiters, the cost of replication is too high and it is difficult to break through technical barriers. In addition, electronic tags have reliable security encryption mechanisms, and China's second-generation resident identity cards also use RFID technology.

In the past decade, RFID radio frequency identification technology has developed rapidly and has gradually been widely used in many traceability and anti-counterfeiting applications such as industrial automation, commercial automation, and transportation control management. With technological progress, the types of RFID based products will become increasingly diverse, and their applications will also become more widespread. It is expected that in the coming years, RFID based technology will continue to maintain a high-speed development trend.
