Abstract
Inferring product activity includes providing a first product having an attached first harmonic tag; directing, at a first area in which the first product is located, a first transmitted signal of a first frequency; and receiving a first return signal of a first return frequency from the first harmonic tag, wherein the first harmonic tag, upon receiving the first transmitted signal, radiates the first return signal, such that the first return frequency is a harmonic of the first frequency. A computer can then infer, based on the first return signal, a first activity in which the first product is being used.
