It is not clear how to evaluate radio frequency identification (RFID) potential for use in production companies supply chains (internal and external). We propose Assessment of RFID Technology (ART) modular method (strategy, tactics, operations, evaluation) and elaborate tactical module (ART-T). ART-T application in a manufacturing company is illustrated. We apply TOPSIS (technique for order of preference by similarity to ideal solution), SCOR (supply chain operations reference) model, linguistic scales, fuzzy sets and questionnaires to answer the question ''which processes should be chosen for RFID-based reengineering and/or improvement''. Research output shows ART-T flexibility and ease of use at factory level.
