RFID technologies are not brand new anymore as a principle of communication using radio frequencies but their application on production and services sector still is uncertain because, in spite of an evident series of advantage, a deep evaluation concerning economical implication has to be made case by case. From this derives that is necessary an experimental activity and this is the way that most of the industries are following at the present moment. An important contribute to this experimental activity and to research can be provided by a test center recently established in University “La Sapienza”: RFID-Lab. This paper aims to describe advantages, disadvantages and functionalities of RFID technologies and to explain which are the activities conducted in RFID-Lab.
