In this project we are going to implement i2c (INTER INTEGRATED CIRCUIT) based smart card system. Here we used at93c46 eeprom as smart card. It is an i2c based EEPROM device. In this project we used smartcard for giving the information about the student in the college. If we implement this system in our country, we can use this same smartcard for multipurpose. Like voter id, license, credit card etc..,.
There are many types of smart cards accessible in market; they are magnetic stripe, bar code. In older days for smart cards applications we were using magnetic strip type memories to read and write data's, but they are less secure.
To increase the security and to improve its performance we decide to go for a i2c based smart card. The at93c46 is integrating the hardware and the software for a unique dedicated application.
This system consists of AT89S52 which is connected to the smart card is connected to the lcd. When we insert a smart card into the memory slot, we give the information of the student in LCD with the help of embedded c program written on at89s52 microcontroller
