An Ambient Assisted Living Platform Integrating RFID Data-on-Tag Care Annotations and Twitter

Although RFID is mainly used to identify objects whose data can then be accessed over the network, passive HF RFID tags do have significant data storage capacity (up to 4K), which can be utilised to store data rather than only IDs. This work explores the potential of storing, accessing and exploiting information on tags both, theoretically, by studying how much data can actually be stored in HF RFID tags, and practically, by describing an NFC-supported platform adopting the data-on-tag approach to improve data management in a care centre. Such platform illustrates two key aspects for AAL: a) RFID tags can serve as temporary repositories of care events whenever a continuous data link is not desirable and b) interactions between RFID wristbands worn by residents and care staff’s NFC mobiles can improve care data management and keep relatives up-to-date with elderly people’s evolution, through a Web 2.0 social service.
