Near field communication (NFC) is a short-range wireless protocol that allows users to connect devices and access content and services by simply holding enabled devices near each other. This paper introduces a user interaction model for NFC enabled applications. Our model specifies that enabled devices take on the properties and context of the objects required in the interaction. This transformation leverages the existing knowledge users have about certain objects and thus can support a number of different applications tied together with simple, intuitive and repeatable interactions. In this paper, we present an overview of the model and the system we have implemented to enable evaluation. We also detail some research challenges we are pursuing.
