Abstract
Systems and methods for the identification, powering and control of products and product packaging. The systems can include a point of sale display having a contactless power supply. The contactless power supply can provide a source of wireless power for products and product packaging. The products and product packaging can include light emitting diodes, e-ink displays and printed speaker circuits that activate as the operating frequency of the contactless power supply varies. Other embodiments include product level sensors, inductive reader networks, printed temperature sensors, product alignment systems, passive identification circuits and methods for controlling operation of the same.
