a: logistics information technology mainly includes: \xd\1, commodity bar coding and scanning system \xd\ barcode technology is an automatic identification technology, which is designed to realize automatic scanning of information. \xd\2. POS (Point of Sales) \ xd \ The basic operating principle of POS system is to first create the commodity data in a computer file, and through the online structure of the computer cash register, the barcode on the commodity can be directly read in through the optical reading device on the cash register equipment (or directly input the code by the keyboard), and then the commodity information can be displayed immediately, thus speeding up the cash register speed and correctness. The detailed information of each commodity sale is automatically recorded, and then returned to the computer by the connection framework. Through computer calculation and processing, all kinds of sales statistical analysis information can be generated as the basis of management. \xd\3, EDI (Electronic Data Interchange) \ xd \ EDI is the direct transmission of standard business documents between enterprise computer systems. Using EDI system can make enterprises communicate and exchange information with their suppliers quickly, realize one-to-one long-term cooperation with suppliers, and help to establish an integrated supply chain logistics management system. \xd\4.

Enterprises can use the Internet to communicate and feedback information to their upstream and downstream enterprises in a timely manner. \xd\5. Radio frequency technology \xd\ Radio frequency technology can improve the level of logistics operation. It can be used in warehousing, transportation and cargo tracking. \xd\6. Satellite communication technology \xd\ Satellite communication technology is used for information transmission, which realizes a large number of rapid information transmission through satellites and is a technology used in the process of logistics information management.
