RFID technology enables us to identify each object and even the container itself.The RFID readers can be placed up to a few meters away from RFID tagged objects.[8]However, current RFID gives all information related to the objects present in the group but they do not provide information on IDs missing from a group.The work mentioned in this paper proposes a method and it will design a system which will determine the unique IDs of objects missing from a group.The proposed methodologically will find out the identification of the missing objects and transmit the desired information in encrypted packet format for secured communication of the information.. Encrypted packets will be of 8-bit size and will be transferred to a remote analyzer through UART of ARM7.The analysis work will be done using serial monitoring software and the information will be displayed on a embedded user interface in encrypted form which will further be decrypted to get the desired information about the missing tags.
