Help : Interfacing AT89C51 With AT24CXX EEPROM

Hello, I am a Third Year Electronics Engineering Student From India. I Am Building a Smart Card Based Student Attendance System Project Using uC ATMEL AT89C51........I Am Using AT24Cxx Series EEPROM As A SmartCard(For Demo Purpose Which Wud Be Further Replaced by GSM Sim ;o) ).........So My Problem Is How Can i Read/Write The AT24Cxx EEPROM Using AT89C51 Microprocessors Easily ?.......

I would have started with a contactless system for this system but if you want to see someone elses homework look at https://www.cs.uct.ac.za/Research/DNA/SOCS/report.html

Thanks For Your Quick Reply.....The Link Is Quiet Useful............And As U Say I Too Would Have Gone For Something Like RFIDs....But I Think It Isnt Possible For Me In Such A Short Time........

Can U Please Tell Me How To Just Read/Write AT24CXX Series EEPROMS Using AT89C51 ?
