Assessing the Need for Storing Data on Radio Frequency Identification (RFID) Tags

Abstract: Radio Frequency Identification (RFID) technology has been used within multiple research projects for identification and tracking of components in the construction industry. Although RFID has on-board data storage capacity, not all the studies used this capacity to store some object-related data directly in the tag. In some of the case studies performed, RFID tag was used only as an identifier for tracking various objects or for matching the related object with the additional information that is stored in a remote database. In this paper, the goal is to determine under which conditions an RFID tag needs to be used as a local data storage unit. To identify these conditions, previous research studies that were performed in the construction industry were investigated. The characteristics of cases that were described in the studies were identified and data storage needs were determined. Also, types of information items that were stored in the tags were identified. The results show in which types of cases RFID was used to store additional data. In addition, the advantages and disadvantages of storing data on the tag and on a remote database were discussed.
