A paper which gives an initial overview to start designing with RFID. “Designing with RFID” by Einar Sneve Martinussen and Timo Arnall, 2009:

The bare RFID tag itself does not offer significant meaning beyond its technical appearance. In order to create meaningful relationships towards these objects, RFID tags must be embedded in an object or signified by shape or sign.


These toys do not go beyond the simplest tag-to-reader interactions, and rely on simply bringing two objects close together to create a resulting digital event.


In the near future these peripherals are likely to enable the growth of content-centric applications that use RFID to connect various forms of media to physical objects, often referred to as tokenbased interaction.


Hiding tags inside objects raises questions about visibility. How can embedded tags be signified by shape, material or sign? How might we use features of an object to guide the user towards the use of the tag. It also exposes the importance of developing design qualities such as shape, materials, build quality and affordances.

Very promising is their digital 3D  explorations in form  variations of physical RFID objects. Used parameters were direction, balance,  ergonomics, similarity and goemetry.
