RFID BASED MULTIPURPOSE SYSTEMOur idea is based on the fact that RFID chips <strong>and</strong> receivers are rapidly becomingpopular <strong>and</strong> have been implemented in various environments. It has been predicted thatthese systems would completely replace the ‗bar code‘ systems till 2030. The primaryfocus <strong>of</strong> this system is the design <strong>and</strong> implementation <strong>of</strong> a cost-effective system ascommercial systems are very expensive <strong>and</strong> also RFID readers are not locallyavailable.Our system is designed on the basic principle <strong>of</strong> Radio Frequency Identification. Thesystem consists <strong>of</strong> three main parts namely RFID reader, passive RFID tags <strong>and</strong> adesktop application. The RFID reader consists <strong>of</strong> an RFID IC, PIC microcontroller withLCD display, an external antenna <strong>and</strong> a USB interface to the host system. Passive tagsare powered up by the radio signal transmitted by the reader antenna whenever the tagis in the vicinity <strong>of</strong> the antenna. Now the activated tag sends its unique identificationnumber to the antenna which is passed on to the RFID IC. The RFID IC, afterperforming necessary adjustments to the received code, communicates it to the PICmicrocontroller. The USB module in PIC transfers this data to the host system where adesktop application is used to read this data <strong>and</strong> upload it to a MySql Database. AnRFID user portal is designed to provide real time access to database through the web.The distinguished feature <strong>of</strong> the system is that it is using ISO18000-6C st<strong>and</strong>ard whichis being used globally for RFID applications <strong>and</strong> all codes <strong>and</strong> algorithms are proprietary<strong>and</strong> sold for thous<strong>and</strong>s <strong>of</strong> dollars. We have developed the same algorithms as freeware.The available ISM b<strong>and</strong> for this st<strong>and</strong>ard is 860MHz-960MHz <strong>and</strong> the read range<strong>of</strong> the system is 5-6 metres.The prototype RFID system has been designed <strong>and</strong> built which is capable <strong>of</strong> assetmanagement in the library. With few modifications, this system can be implemented forlab security, attendance <strong>and</strong> vehicle identification.Syndicate Members: Javeriah Iftikhar AbbasirNaumana AyubSaad Riaz QaziMoeed Bin ShafiqSupervisor:Asst Pr<strong>of</strong>.
