Conventionally, RFID tags are used to identify uniquely objects whose data can then be accessed over the network. This implies that the data storage capacity (up to 4K) of HF RFID has usually been neglected. In contrast, this work follows the data-on-tag approach, combining RFID and NFC technologies, with the aim of improving care data management in assistive environments. It analyzes the potential and feasibility of writing and reading small breadcrumbs of information at/from residents’ RFID wristbands, as a solution to the inherent difficulties of gathering, processing and disseminating data within a multi-user, multi-stakeholder assistive environment such as a residence or a caring home. As a result of this, an AAL platform is extended to deploy what we have termed as the “RFID breadcrumbing” interaction metaphor.
