Introduction

• I will first give a brief introduction to the
  various technologies employed in the project
• I will then detail the application itself

3
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

4
Overview of the System
5
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

6
Tag anatomy
7
RFID Tag Structure

• Antenna

Power Supply
Memory Cells
Control Logic (Finite State machine)
Tx Modulator
Rx Demodulator
Tag Integrated Circuit (IC)
8
Function of an RFID Transponder

• Hold a unique identifier
• Respond to requests for the data it carries

9
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

10
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

11
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

12
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

13
PHP

• Its a embedded scripting language (encoded in
  HTML)
• Scripting language interacts with databases and
  dynamically generates web pages
• Invokes SQL commands to interact with database

14
Visual Basic

• Functions
• -Interface with the RFID reader
• -Display the results of the SQL database
  queries
• (dynamically generated web pages)

15
Visual Basic

• The MSComm control handles the communication with
  the RFID reader
• Visual Basics 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

20
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.

21
Conclusions

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