The most widely used automatic identification technology in logistics technology is barcode technology and radio frequency identification technology. Specifically as follows:
Radio frequency identification technology (RFID) is a kind of automatic diagnosis technology, through the wireless radio frequency way to carry on the non-contact two-way data communication, uses the wireless radio frequency way to the record media (the electronic label or the radio frequency card) to carry on the read-write, thus realizes the recognition target and the data exchange process.
RFID technology has a wide range of applications, such as logistics, retail, medical, transportation and other fields, can realize the item tracking, inventory management, asset tracking, access control management and other functions.
Automatic identification technology is a highly automated data collection technology based on the development of computer, optical, mechanical, electrical and communication technologies. It is through the application of certain identification devices, automatically obtain the relevant information of the recognized object, and provide to the background processing system to complete the relevant follow-up processing of a technology.
It can help people quickly and accurately carry out the automatic collection and input of massive data, and has been widely used in transportation, warehousing, distribution and other aspects. After nearly 30 years of development, automatic identification technology has developed into a comprehensive technology composed of barcode identification technology, smart card identification technology, optical character recognition technology, radio frequency identification technology, biometric identification technology.
And is developing in the direction of integrated applications. Barcode recognition technology is currently the most widely used automatic identification technology, it is the use of photoelectric scanning equipment to read the bar code symbols, thereby realizing the automatic entry of information. Barcode is a set of specific rules arranged in accordance with the bar, empty and the corresponding characters composed of symbols that represent certain information. Different code systems, bar code symbols are composed of different rules.
