摘要
Tags encode information by means of spatial inhomogeneities that may be detected in the time domain; in effect, characteristics in space are transformed into time for sensing purposes. Such tags may be very inexpensively produced yet carry appreciable quantities of data. The inhomogeneities may be obtained by simple physical modifications to, or externally applied field biases operating on, materials that are very inexpensive to procure.
