Smart ration card using RFID, biometrics and SMS gateway

In this paper, we have proposed a smart ration card using Radio frequency identification (RFID) technique, biometrics and SMS gateway to prevent the ration forgery. In this system, a RFID tag is used that carries family member details and the customer needs to show this tag at the ration shop. The user will also have to provide thumb impression on the biometric machine. If the user is found authentic then the quantity of ration to be given to customer according to the total number of family member will be displayed on the LCD display This smart ration card is free from theft and forgery as the information about the delivered ration will be sent directly to the government and customer through SMS gateway.
