Kjetil Nordby describs in her work “Multi-field relations in designing for short-range RFID“, a good interaction approach for RFID.

Four types of relations are distinguished:

  1. one-way: i.e. activating  sub-fields (command buttons) by selecting parent field
  2. two-way: i.e. selecting radio buttons on a smart poster
  3. sequence: copying information from one tag to the other; related to Direct Manipulation techniques (copy&paste, drag&drop)
  4. multiple relations: two or more simultanous field intersections (coupled presence), i.e. two phones placed on tags in separate locations instantly set up a video conference between the phones
