This paper presents a modified RFID application in e-commerce security for personal or logistic uses by demonstration of Mother and Children Coordination Management. RFID readers are installed at public sites to identify different groups of RFID tags. All child tags are supposed to follow the mother tag in uncompromising conditions. Any inadequate combination to be captured by the public installed RFID readers will generate an alert to the server monitor or site security. Telephone numbers,with nation code, area code and number, are worldwide unique code to adopt as ciphers. The popularization of the proposed RFID family coordination management system by public or corporation investments is recommended to enhance e-commerce in added values. The proposed system is also valuable to airport luggage handling system to reduce luggage lose.
