Abstract—

Technologies of identification by radio frequencies
(RFID) and their standardization with the Electronic Product
Code (EPC) architecture experience a fast development. After
briefly introducing the common terminology of the RFID field
and a short presentation of its current standards, this paper
presents one possible application domain: the tracking of objects.
In this context, the distributed software architecture of a J2EE
based assets tracking application, called RFIDLocator, is further
described. RFIDLocator allows to trace electronically labeled
objects within a predefined area (e.g. a building, a campus, a
site, ...). Indeed, when tagged objects are moved, the monitoring
information system is automatically informed thanks to readers
deployed in their environment.
As the number of assets can increase dramatically, this kind of
application has high requirements for scalability and reliability
which are supported through the use of solid object oriented
software systems (Enterprise Java Beans technology along with
an implementation of the Event Manager standard). Some critical
remarks about this emerging technology, the important questions
it raises and the barriers it has to overcome to be fully accepted
conclude this paper.
