Now a day's mobile technology plays key role, in various environments identification of objects can be done manually, to improve the efficiency of an identification of objects the authors are using RFID tags. RFID tags track objects in supply chains, and are working their way into the pockets, belongings and even the bodies of consumers. Tag collision occurs while two or more than two tags deliver their Unique IDentification (UID) to the reader. Since collision, which would significantly affect the efficacy of RFID, has been one of the major study issues for RFID technology, they have developed a solution, Bit Competed Algorithm (BCA), to solve the collision problem occurred in RFID system and consequently improve the efficacy of RFID.
