Combining RFID and NFC Technologies in an AmI Conference Scenario

The significance of sensing technologies in ambient intelligence is crucial. These technologies allow us to acquire context awareness automatically by knowing two basic features of context: who and where. They thus offer services in consonance with the characteristics of users and produce savings in the interactive effort. In this work we present an approach through a combination of: radiofrequency identification (RFID) and near field communication (NFC) technologies. We compare both, analyzing the requirements and the advantages of each one, defining processes that each technology offers. The first allows implicit user perception and triggering service, while by the second one we can have user localization on a point, and bring about an innovative way of interaction by contact.
