The problem
3I-CENTRIC 2008 October 26-31, 2008 - Sliema, Malta
• Registration of all students attendance made in paper in
every class.
• Loss of time for students and the teacher.
• Validation and insertion of data is done manually.
• Lack of knowing exactly the students who attended a
particular class.
• More than 200 classrooms and approximately 3000
students.
Proposed solution
4I-CENTRIC 2008 October 26-31, 2008 - Sliema, Malta
• Automate the whole system of students attendance registration
using RFID.
• Convert the students identification cards for cards tagged with an
RFID tag.
• Installation of one RFID reader per classroom.
• Find a cheaper reader due the large number of classrooms.
• Connect all readers to the educational institution LAN.
• RFID readers powered by Power over Ethernet (PoE).
RFID reader selection - Different approaches
5I-CENTRIC 2008 October 26-31, 2008 - Sliema, Malta
• First:
– UHF readers and tags.
– Student is automatically identified as he enters in the classroom.
– Could violate student privacy.
– Very expensive.
• Second:
– LF readers and tags.
– Student need to place his card near the RFID reader to register his presence.
– Cheaper solution.
RFID reader selection - Search for an appropriate reader

• Cheaper readers work through RS-232, Wiegand or
USB.
• The price suffer a large increase whenever a LAN
interface exists.
• Readers with LAN interface have dozens of extra
features that aren’t necessary.
• Few readers work with PoE.

Proposed system architecture
8I-CENTRIC 2008 October 26-31, 2008 - Sliema, Malta
RFID Middleware
• Abstraction layer between educational institution’s
data base and servers.
• Dynamic-Link Library (DLL) file.
• Methods to collect necessary information from the
DBMS, from the RFID and web services server.
• Methods return information in XML format.
• Flexibility

Results

• Test scenario with 5 classrooms.
• All connected to the LAN.

Conclusions and future work
• Generic architecture of an intra-connected network of RFID readers
within an educational institution.
• The need of an RFID reader that can transmit data acquired over
Ethernet in a distributed environment at a very attractive price.
• Implementation and validation to the whole architecture with one
reader for every classroom.
• Providing more services to automate more educational institution’s
processes.
