The ghost in the field

Immaterials: The ghost in the field is a project that explores the spatial qualities of RFID, visualised through an RFID probe, long exposure photography and animation:

“There are 4 billion RFID tags in the world. They may soon outnumber the people. Readers and tags are increasingly embedded in the things and environments in which we live. How do readers see tags? When we imagine RFID and their invisible radio fields, what should we see? Immaterials explains the experiments we have performed to see RFID as it sees itself.” (Timo Arnall of the Touch project and Jack Schulze of BERG)
