RFID(Radio Frequency Identification)
Consists of reader and tag wireless non-contact use of radio-
frequency electromagnetic fields to transfer data, for the purposes of identifying and tracking tags attached to objects
Used in many industries, such as transportation, health care, education

RFID middleware
It coordinates RFID readers, process the vast amount of captured data.
It handles the communication between readers and application software.

Problems
Most of the current existing RFID middleware are sophisticated and expensive
> Simplify in structure and reduce in scale to suit manufacturing scenarios It needs to be more agile and
responsive to the modern changing market
> Design it to be flexible, modularized, rather than full-featured and sophisticated

Reader service control
access RFID readers directly at some situations web service mode : implemented and
published for back-end applications, which include tag reading and writing
messaging mode : domain applications interact with smart agents through AIS to exchange information between applications and software agents
