The role of RFID middleware

RFID middleware conveys information from one program to another program or multiple programs, which is the transfer of data information between the application system and the RFID system. It is worth mentioning that in addition to transmitting information, RFID middleware also includes services such as security, data interpretation, error recovery, data broadcasting, finding cost-compliant paths, and locating network resources. RFID middleware solves the problems of RFID data security, data format conversion and reliability. It shields the diversity and complexity of RFID equipment, and provides a strong support for the background business system, thereby driving wider and richer RFID applications.

RFID middleware acts as an intermediary between RFID tags and applications, and directly calls the standard general interface given by the RFID middleware framework from the application side to operate on tag data within the scanning range. One end of the middleware is connected to the reader data interface, and the other end is connected to the application program data interface. It effectively realizes the data transfer between the application program and the RFID electronic tag, and reduces the difficulty of data transfer and data reading. It not only reduces the complexity and development difficulty of the application program, but also makes the system more convenient for optimization, improvement and system maintenance.

Therefore, even if the database software or back-end application program storing RFID tag information is added or replaced by other software, or even when the types of RFID Readers increase, the application side does not need to be modified. This not only effectively solves the problem of data read rate, but also saves other problems such as the maintenance complexity of many-to-many connections. In the future, RFID middleware will have a very good development prospect in the application of service-oriented architecture and business information security issues.

Although RFID technology still has some technical and application problems such as low reading rate, we believe that the development of RFID will be better and better in the future. In the near future, China, as the global manufacturing base, will be the world's largest RFID application market in the future.
