Abstract
A contactless bi-directional device including first and second generally mutually electromagnetically decoupled contactless loop antennas which are arranged in at least partially mutually overlapping orientation, first and second contactless communication chips, each of the first and second communications chips being connected to a corresponding one of the generally mutually electromagnetically decoupled contactless loop antennas, thereby providing bi-directional communication.
