Method for the detection of modified information patterns of a capacitive information carrier by the use of capacitive detection means

Abstract

The invention relates to a method for the detection of modified information patterns of a capacitive information carrier comprising at least one electrically conductive material forming at least one modifiable electrically conductive pattern, wherein information is encoded within the characteristics of the electrically conductive pattern. The method comprises at least the steps of modifying the characteristics of the electrically conductive pattern and capacitively detecting a second information pattern encoded within the characteristics of the modified electrically conductive pattern. In a further aspect, the invention relates to a capacitive information carrier for use in the method according to the invention and a method for manufacturing a capacitive information carrier for use in the method according to the invention.
