Abstract: The invention relates to an identification system, comprising an information carrier or a group of such information carriers, which allow a clear association of information. The invention further relates to the use of said information carriers, and to a device for reading said information carriers, wherein the information carriers are associated with a random action of a data processing system by way of the structured information layer thereof or can trigger such action. The invention furthermore relates to information carriers for access control systems, payment systems, ticket systems, and marketing application. According to the invention, overlaps of the information layer can be provided by applying additional layers, which achieve several advantages according to the invention, such as optically rendering the information layer unrecognizable, and resulting increased safety of the information carrier against manipulation.

Abstract: The present invention relates to a method comprising providing one or more information carrier(s) with a dielectric and/or conductive pattern and a detection device having a capacitive touch screen and inducing an interaction between the information carrier and the touch screen, wherein the interaction is based on a difference in the dielectric coefficient and/or the conductivity of the pattern and generates a touch signal and wherein the interaction is induced by relative motion between the information carrier and the touch screen. The invention further relates to a system comprising an information carrier comprising a dielectric and/or conductive pattern which encodes information and a detection device having a touch screen; the detection device is able to decode the information upon interaction between the information carrier and the touch screen, wherein the interaction is caused by a difference in the dielectric coefficient and/or the conductivity of the pattern.

Abstract: The invention relates to a data carrier or a group of such data carriers which allow for accurate correlation of information, the use of these data carriers, as well as a reading device, by means of which a data carrier via its structured information layer is associated with an action of a data processing system or can trigger the said action. More particularly, the invention also relates to a game card system that learns the unique playing characteristics of players and allows the processing of other game-related data, whereby the system comprises the use of game cards and collector cards over the Internet (online) as well as via a local data processing system (offline), and where, accordingly, the invention relates to a particularly preferred embodiment, that is a combination of the traditional collector card game with computer and video games.
