Introduction
I will first give a brief introduction to the various technologies employed in the project
I will then detail the application itself
National University of Ireland, Galway
Project Goal
Identification of the Patient through an RFID wrist tag
Storage of Patient Medical details in a web based database
Retrieval of patient information from the database using the RFID tag number

RFID
Two components:-RFID Transponder-RFID Reader
Every object has an RFID transponder, holding identification information
The reader retrieves the identification information from the RFID tag

Function of an RFID Transponder
Hold a unique identifier
Respond to requests for the data it carries
National University of Ireland, Galway
RFID Reader
Interrogate tags via RF communication Consist of a RF module, a control unit, and a
coupling element They have a secondary interface to
communicate with a host system Reads tags located in hostile environment
and obscured from view
National University of Ireland, Galway
RFID Conclusions
Each patient will have an RFID tag
The RFID Tag will hold a unique identifier
This identifier will be retrieved by the RFID reader
National University of Ireland, Galway
Web Based Database
The web-server takes the RFID tag number, searches the database and returns the patient details
MySQL – Database that holds the patient information
PHP – Database Querying script
National University of Ireland, Galway
MySQL
Standard database programming language used for creating databases
It provides methods for updating and retrieving information
The information is divided into logical units called tables
The tables include personal information, medical information and nurses’ observations
National University of Ireland, Galway
PHP
It’s a embedded scripting language (encoded in HTML)
Scripting language interacts with databases and dynamically generates web pages
Invokes SQL commands to interact with database
National University of Ireland, Galway
Visual Basic
Functions: -Interface with the RFID reader-Display the results of the SQL database queries (dynamically generated web pages)
National University of Ireland, Galway
Visual Basic
The MSComm control handles the communication with the RFID reader
Visual Basic’s Web Browser component handles the displaying of the PHP and HTML pages

Functionality of the System
Update and retrieve patient personal details Update and retrieve patient medical details Upload and retrieve patient multimedia data
such as x-rays, pictures, etc. View previous medical details
National University of Ireland, Galway
Conclusions
System successfully merges the technologies of RFID and web-based database systems
The RFID tag provides a secure and robust method for holding the patients identifier.
The web-based database allows for the centralisation of all patient records.

Conclusions
System has potential applications in many other sectors including:
-Airline passenger/baggage tag-Part recall data-Product tracking-Calibration data-Inventory control
