Radio frequency technology
The most important advantage of radio frequency identification systems is non-contact recognition, which can read through the harsh environment where snow, fog, ice, paint, dust, and bar codes cannot be used, and the reading speed is extremely fast, in most cases less than 100 milliseconds. The ability to write active RFID systems is also an important advantage. Can be used for process tracking and maintenance tracking and other interactive services.
The main issue that hampers the development of RFID systems is incompatible standards. The main manufacturers of radio frequency identification systems provide dedicated systems, resulting in different applications and different industries adopting different vendors' frequency and protocol standards. This confusion and segregation have already constrained the growth of the entire RFID industry. Many European and American organizations are working to solve this problem and have achieved some success. Standardization will certainly stimulate the significant development and widespread application of radio frequency identification technology.
The essence of logistics management is to achieve the two goals of reducing costs and improving service levels through the management of the entire logistics process. How to ensure that the right customers get the right products at the right time and in the right place with the right cost and the right conditions has become the highest goal pursued by logistics companies.
In general, the value of the company's inventory accounts for about 25% of the total assets of the company and accounts for more than 50% of the company's current assets. Therefore, the core of logistics management is the management of inventory in the supply chain.
The use of radio frequency identification technology in transport management requires only the installation of electronic tags on the outer packaging of goods, and the installation of readers at transport checkpoints or transit stations to enable the visual management of assets. At the same time, the owner can access the on-the-spot visualization web page according to his authority to understand the specific location of the goods, which is of great significance in improving the service level of logistics companies.
1. Quick scan. The RFID reader can recognize and read several RFID tags at the same time!
2. The size is small and the shape is diversified. RFID is not limited by size and shape in reading, and does not need to match the fixed size and print quality of the paper for reading accuracy. In addition, RFID tags can be developed in smaller and more diverse forms to be applied to different products.
3. Pollution resistance and durability. The carrier of traditional bar code is paper, so it is easily contaminated, but RFID is very resistant to substances such as water, oil and chemicals. In addition, because barcodes are attached to plastic bags or over-wrapped cartons, they are particularly vulnerable to breakage; RFID tags store data in the chip and are therefore protected from contamination.
4. Can be reused. Now that barcodes cannot be changed after printing, RFID tags can repeatedly add, modify, and delete data stored in RFID tags to facilitate information updates.
5. Penetrating and non-barrier reading. When covered, RFID can penetrate non-metallic or non-transparent materials such as paper, wood, and plastic, and is capable of penetrating communication. The bar code scanner must be able to read the bar code at close range and without object obstruction.
6. The data memory capacity is large. The capacity of one-dimensional barcodes is 50 Bytes, the maximum capacity of 2D barcodes can store 2 to 3,000 characters, and the maximum capacity of RFID is a few MB. With the development of memory carriers, the data capacity is also expanding. The amount of data required to carry future items will increase, and the demand for the capacity of the labels to expand will increase accordingly.
7. Security. Since RFID carries electronic information, its data content can be protected by passwords, making its content less susceptible to counterfeiting and alteration.
RFID has attracted attention due to its features such as remote reading and high storage capacity. It can not only help a company significantly increase the efficiency of goods and information management, but also allow sales companies and manufacturing companies to interconnect, so as to receive feedback information more accurately, control demand information, and optimize the entire supply chain.
