RFID technology has great potential to improve the benefits of supply chain management. Auto- manufacturing is a competitive industry that every player of it needs great operation efficiency to gain competitive advantage to survive. RFID systems are good enhancements to supply chain processes, Therefore it's obvious that every industry has to pay great attention to this IT solution, and in this case the auto industry which is the industry of industries is not an exemption. Auto industry is one of the areas which need the help of information technology and its solution - RFID- to track each auto part from the beginning to the end of its supply chain. In this research we study the key dimensions of factors influencing on RFID technology development in the supply chain of Iran's auto industry by using the structural equation modeling (SEM) method. The results indicate that security and technology dimensions have greater influence on RFID development in the nation`s auto industry than other dimensions. Manuscript profile
