Patent ID: 7883408

Claim:
A station for reading and/or writing in a memory of a token having an electronic circuit, said token being arranged in a stack of two or more tokens, said station comprising: a token storing system; an antenna arrangement comprising first and second antennas; at least one of the first and second antennas comprising antenna loops disposed adjacently and being at least partly superposed on each other so as to define an enlarged reading and/or writing area in which transmission quality is substantially homogeneous, each antenna loop delimiting an interior surface located substantially within a single plane when active; and a communication unit adapted to exchange information with the memory via the antenna arrangement when said token is arranged in the token storing system in an orientation that allows for communication, said communication unit adapted to select one of said antennas in said antenna arrangement to be active, said communication unit configured to selectively communicate with the memory of each token in said stack of two or more tokens in said enlarged reading and/or writing area associated with said active antenna, wherein the station is structured and arranged to discriminate between two tokens or among more than two tokens when stacked.
