Abstract: Public distribution system i.e. Ration distribution system is one of the widely controversial issues that involves corruption and illegal smuggling of goods. This fraud is increases due to the manual involvement and manual measurement, this fraud occurs due to the wrong entries in register without the knowledge to the ration card holder because of this large amount of money of government get wasted and needy person remains needy. To avoid this fraud we have developed system by using Microcontroller, in this system we have proposed smart card instead of ration card and also provide smart card detector to verify correct person or family member if the detected person is correct then next step takes place. In this system user database already stored in the system. GSM is used to send the information to ration card holder and also to the government.
