Application field
1. Logistics
Logistics warehousing is one of the most potential application areas of RFID. International logistics giants such as UPS, DHL, Fedex, etc. are actively experimenting with RFID technology, with a view to large-scale application in the future to improve their logistics capabilities. Applicable processes include: cargo tracking in the logistics process, automatic information collection, warehousing management applications, port applications, postal parcels, express delivery, etc.
2. Transportation
There have been many successful cases in taxi management, bus terminal management, and railway locomotive identification. [9]
3. Identification
RFID technology is widely used in personal identification documents due to its fast reading and difficult to forge. Such as the development of the electronic passport project, my country's second-generation ID card, student card and other various electronic documents. [9]
4. Anti-counterfeiting
RFID has the characteristics of being difficult to forge, but how to apply it to anti-counterfeiting still requires active promotion by the government and enterprises. The applicable fields include the anti-counterfeiting of valuables (tobacco, alcohol, medicine) and the anti-counterfeiting of tickets.
5. Asset management
It can be applied to the management of all kinds of assets, including valuables, items with large quantity and high similarity, or dangerous goods, etc. As the price of tags decreases, RFID can manage almost all items.
6. Food
It can be applied to the management of fruits, vegetables, fresh food, food, etc. The application in this field requires innovation in label design and application mode.
7. Information statistics
With the use of radio frequency identification technology, information statistics has become a simple and fast task. The query software of the archives information management platform sends out the statistical inventory signal, and the reader quickly reads the data information and related storage information of the archives, and intelligently returns the acquired information and the information in the central information database for proofreading. For example, for files that cannot be matched, the manager will use the reader to carry out on-site verification, adjust the system information and on-site information, and then complete the information statistics work.
8. Check the application
When querying file information, the file manager uses the query management platform to find the file number. The system reads the data in the central information database according to the file number. After verification, it sends out the file out signal, and the storage management platform intelligently recognizes the file. The function module will combine the file number corresponding to the relevant storage number to find out the specific location of the file. After the manager sends out the file out-of-warehouse signal, the indicator light on the storage location will immediately light up. When the data is out of the library, the radio frequency identification reader will feed back the acquired information to the management platform, and the manager will check again, check that the outgoing files and the checked files are the same, and then go out of the library. Moreover, the system will record the time when the information is out of the library. If the feedback file does not match the query file, the alarm module in the security management platform will transmit an abnormal warning.
9. Security control
The security control system can realize the functions of timely monitoring and abnormal alarm of the archives, so as to avoid the destruction and theft of the archives. When archives are borrowed and returned, especially physical archives, they are often used for exhibitions, evaluation and inspection, etc. The manager carefully checks the returned archives and verifies with the information before the archives are lent, and can find out whether the archives are damaged or missing in time
development trend
1. Trends in RFID tags
With the formulation of standards, the wide range of applications, the increase in the number of applications, the continuous improvement of technology, and the rapid advancement of technology (for example, in the case of books, conductive ink is used to directly print radio frequency identification antennas on the cover or copyright page). The cost will be lower; secondly, the identification distance will be longer, even a passive radio frequency identification tag can reach tens of meters; the volume will also be smaller. [2]
2. High frequency
Compared with the low frequency system, the UHF radio frequency identification system has the advantages of long identification distance, faster data exchange speed, higher forgery difficulty, stronger anti-interference ability to the outside world, compact size, and with the reduction of manufacturing costs and high frequency With the further improvement of technology, the application of UHF systems will be more extensive.
3. Networking
In some applications, the data collected by different systems (or multiple readers) needs to be processed in a unified manner, and then provided to users. For example, we use second-generation ID cards to pick up train tickets at automatic ticket machines, which requires radio frequency identification System network management to realize the remote control and management of the system. [2]
4. Multifunctional
With the continuous improvement and popularization of mobile computing technology, the development trend of RFID reader design and manufacturing will be multi-function, multi-interface, multi-standard, and to the direction of modularization, miniaturization, portable, and embedded; at the same time, Multi-reader coordination and networking technology will become one of the future development directions.
