Comparison of Radio Frequency Identification Technology and Bar Code

-

Why is RFID technology superior to barcodes?

RFID technology and bar code are two different technologies, have different applicable scopes, and sometimes overlap. The biggest difference between the two is that barcodes are 'visual technology'. The scanner works under the guidance of people and can only receive barcodes within its field of view. In contrast, radio frequency identification does not require seeing the target. The radio frequency tag can be read as long as it is within the range of the receiver. The barcode itself also has other shortcomings. If the label is scratched, contaminated or peeled off, the scanner will not be able to identify the target. The barcode can only identify the producer and the product, but cannot identify the specific product. The barcodes affixed to all the same product packaging are the same, and it is impossible to identify which products expire first.

What is the difference between RFID technology and barcode?

Conceptually, the two are very similar, and the purpose is to quickly and accurately confirm and track the target object. The main difference is as follows: whether it has the ability to write information or update the memory. The barcode memory cannot be changed. Unlike a bar code, a radio frequency tag cannot be copied with its unique identifier. The role of the label is not limited to the field of view, because the information is transmitted by radio waves, and the bar code must be in the field of view. Due to the low cost of bar codes, a complete standard system, which has been spread around the world, it has been generally accepted. On the whole, radio frequency technology is limited to a limited market share. At present, a variety of barcode control templates are already in use, and there are also different standards for radio frequency in terms of obtaining information channels.

At present, in terms of cost, what is the difference between labels and barcodes?

Because of the different components, smart labels are much more expensive than barcodes. The cost of barcodes is the cost of barcode paper and ink. Active RF tags with memory chips cost more than US$2, and passive RF tags cost more than US$1. However, the price of a label without a built-in chip is only a few cents. It can be used in situations where the data information requirements are not so high, and at the same time it has the anti-counterfeiting function that the barcode does not have.

VANCH RFID intelligent warehouse management system is an informatized, intelligent and standardized system for unified management and analysis of RFID intelligent warehouses relying on mutual cloud computing, big data, RFID technology, database technology, AI, and video analysis technology. As the degree of automation in warehousing is getting higher and higher, the requirements for each operation link are getting higher and higher. Like the use of forklifts, the original method depends on human eye recognition and memory, which will inevitably be full of loopholes, and with the degree of intelligence in warehousing To improve recognition accuracy and efficiency, it has become a must-do option to install RFID readers on forklifts to improve recognition accuracy and efficiency. RFID forklift modification is to install RFID readers, antennas, and industrial terminals on the forklift to realize that the forklift can automatically identify the location information and product information i

 In the past 100 years (l906-2005), the average global surface temperature has increased by 0.74 degrees Celsius. In the next 20 years, the global temperature will increase by 0.2 degrees Celsius every decade. Climate warming has become a problem that can not be ignored and has a direct impact on global production and life. Some countries and regions have begun to study the Countermeasures of low-carbon transportation, such as refining the classified management of vehicles with different emission standards, using scientific and technological means and tax system to control carbon emissions, etc. For example, countries and regions such as Britain, Sweden, Germany, Italy and Norway in Europe, Singapore, Tokyo, Taiwan and Hong Kong in Asia, and Australia have established low-carbon transportation areas, low emission areas, green transportation areas and clean demonstration areas to ensure regional air quality and encourage the use of clean vehicles. RFID technology is an automatic identi

Application of Gallium Nitride in Radio Frequency Electronics

In recent years, due to the application of 5G, everyone's attention to RF GaN has increased. Qorvo also believes that GaN is very suitable for providing the high frequency and wide bandwidth required by the millimeter wave field. It can meet the performance and small size requirements, as shown in the figure below. Applications that use the millimeter wave frequency band require highly directional beamforming technology (beamforming focuses the radio signal into a strong directional beam, thereby increasing power and minimizing interference on user equipment). This means that the RF subsystem will require a large number of active components to drive a relatively compact aperture. GaN is very suitable for these applications, because it provides strong performance in a small package size is one of its most notable features. According to a report by Yole, an internationally renowned analysis organization, in early June, the GaN radio frequency industry started with silicon carbide-bas
