RFID tagging is used in supply chain management as an alternative to barcode technology. It ensures the efficiency and speed of the process [1]. Tags do not require line-of-sight to decipher purposes. It can be read through the plastic, human body and wood. RFID uses radio waves to communicate and should be in reader 's read range which varies according to the equipment [2]. RFID ensures that every item in the correct position without any errors.It makes supply chain system is very great also improve the overall reliability and efficiency of the supply chain. It provides updated information on the entire supply chain in real time. RFID can really give a lot of advantages in supply chain. Provide the real time and up to date information across the entire supply chain [3].
