System and method for retrieving information from an information carrier by means of a capacitive touch screen

摘要

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.

1. A method with the following steps:
a. providing one or more information carrier(s) with one or both of a dielectric pattern defining areas or regions having different dielectric coefficients and a conductive pattern defining areas or regions having different conductivities; and b. causing a touch signal to be generated at a touch screen of a detection device in response to an interaction between the information carrier and the touch screen, wherein the interaction is based on one or both of a difference in the dielectric coefficients of the dielectric pattern and a difference in the conductivities of the conductive pattern.
