In the present day, when information is the key to success, commercial and
governmental organizations are increasingly required to secure their critical data and automate the
process. First introduced by Texas Instrument (TI), Radio Frequency Identification (RFID) is
becoming a hotspot in the industry. Initially, it was considered as a bar code replacement. Now,
its applications are far from this [1]. People have always used individual traits for
identification techniques that have been around for centuries, such as passwords and signatures [2].
RFID has also helped to overcome the assailable signature method which is notoriously
insecure and can be ignored. Here we present an architecture of RFID-based GECS system which
is developed for monitoring and tracking the event of entrance of employees in an
organization. As it is a network system with two module architectures: GECS client and GECS server,
the guaranteed network communication link is an integral part of the system. The paper
emphasizes the development of a TCP/IP protocol-based application software to communicate the
unique employee's identity (RF tag) between two mentioned modules. The paper first gives
an overview of the RFID technology and then describes the complete architecture of the
GECS system, followed by the architecture of the GECS system's TCP client-server development.
It also presents the results before concluding.
In RFID, identification of any asset living or nonliving is done without any direct
contact with the automatic data collection where an RFID reader reads information in a tag.
This automated approach enables the electronic labeling and wireless identification of
objects using radio frequency communications. RFID [3, 4] technology has been used in various
areas including transportation and logistics, manufacturing and processing, inventory and
retail, etc. From the functional point of view, an RFID system consists of three components: the
RF reader with antenna, RF tag and the application software.
In accordance with the working and distributed nature of the GECS system, we model
the entire system as per the block diagram given in Figure 1. The entire system is in two
chunks of hardware, running the application software which is developed as per the
client-server algorithm. |
