Application Of RFID Technology In Logistics Of Valuable Items

- Jun 08, 2018-


With the rapid development of economy and microelectronics technology, people have put forward higher requirements for the reliability and security of logistics services. When the Consumers Association investigated the existing problems in the logistics industry, it was discovered that the logistics company lost the goods in the process of transporting valuable goods commissioned by consumers, and the logistics companies suffered more and more losses. Therefore, the safety of valuables in the logistics process is particularly important. RFID technology is a non-contact automatic identification technology. It has strong tracking and traceability capabilities and can timely acquire cargo information so that measures can be taken in time to prevent the loss of valuables from being lost.

1.RFID Technology Introduction

Radio frequency identification technology (RFID), also known as electronic tag, is a non-contact automatic identification technology. It automatically recognizes target objects and obtains relevant data through radio frequency signals, and does not need to establish mechanical or optical between the identification system and a specific target. contact. RFID can identify high-speed moving goods and can identify multiple tags at the same time, and the operation is quick and easy. RFID is a simple wireless system. It usually consists of three basic components. As shown in Figure 1, they are tags, readers, and antennas. In the actual application process, the electronic tag will be fixed on the surface or inside of the identified goods. When the target goods with the electronic tag enter the reader's readable section, the reader will automatically acquire the information given in the electronic tag. Come out, so as to realize the automatic identification of goods.

2.Radio Frequency Identification Technology Working Principle

The basic working principle of RFID is as follows: When the goods loaded with electronic tags enter the readable area of the reader, the electronic tags will transmit the information in the electronic tags back to the reader according to the requirements of the query signals issued by the reader, and the reader receives the tags. After the electronic tag transmits the information back, it identifies the information stored inside the electronic tag and transmits the information to the central database for further processing, thereby completing the information inquiry, charging, management and other applications of the goods.

3.Significance of RFID Technology in the Application of Valuable Goods Logistics

RFID technology can improve the traceability and traceability of valuables in the logistics process, obtain relevant information of goods in a timely manner, and improve the safety of valuables in the logistics process. The application of RFID technology in the logistics of valuables is of great significance.

3.1 Automatic identification of valuables

A tag that records the name, weight, value, quantity, etc. of valuables is installed on the packaging container of valuables. When passing through the traffic entrance equipped with a reader, the reader will automatically read the information on the RFID tag and realize the information. The dynamic tracking and management of valuables has enhanced the work efficiency and information sharing of the logistics process of valuables, reduced the labor intensity of workers, and reduced cargo damage.

3.2 Application of Electronic Seals

The traditional seals are all artificial seals, which have a certain degree of security on the safety of valuables. When the valuables are in the handover process, they need to verify the complete state of the seal and record the transfer status of the seal in order to determine the division of responsibilities. Such artificial seals can only record the information on the logistics status of valuables, but cannot record real-time information on the time, location, and damage status of valuables. The use of RFID technology electronic seals can make up for this defect of artificial seals. After the electronic seal has been combined with GPS technology, it will be able to send information about the state of valuables and the surrounding environment to the relevant management personnel in a timely manner. For example, when valuables are destroyed and freight routes are changed or delayed, managers will get relevant information. The use of such electronic tags has improved the transparency and safety of the logistics process of valuables and improved the tracking and tracing capabilities of valuables in the logistics process.

4. Application of RFID technology in the logistics process of valuables

(1) The cost is higher. RFID tags are relatively expensive compared to ordinary bar code labels and are several tens of times larger than ordinary bar code labels. If the volume of goods is large, the cost of the labels will be too high, which greatly reduces the enthusiasm of companies in using RFID.

(2) The standards are not uniform. RFID technology has not yet formed a globally unified standard. Due to the coexistence of various standards in the market, RFID of different companies' products are incompatible with each other, which in turn leads to confusion in the application of RFID technology.

(3) The technology is not mature enough. RFID technology is not yet very mature because of its short time. For example, due to the retroreflective nature of ultra-high frequency RFID tags, it is difficult to apply RFID tags to metals and liquids.

(4) The confidentiality is not strong. The confidentiality problems faced by RFID systems are mainly manifested in the fact that electronic tag information is illegally read and maliciously tampered with, which is a major obstacle to the use of RFFD systems.

5. Conclusion

The current obstacles in the promotion of RFID technology include high costs, immature technologies, and inconsistent standards. These obstacles will gradually be resolved with the passage of time and technological progress. The application of RFID technology to the logistics of valuables will enable logistics processes and even the entire supply chain to reach more accurate, more detailed, and more timely real-time information on cargo logistics. Better transparency. As RFID technology more economically obtains the logistics information of the goods, it may replace the use of bar codes in all aspects of logistics. In the future, RFID technology will greatly improve the service quality of the entire logistics process, speed up the flow of goods and reduce the operating costs of logistics.
