The invention relates to a capacitive information carrier in which information is encoded by an information pattern comprising a first and a second electrically conductive area on an electrically non-conductive substrate, wherein each conductive area comprises one or more sub-sections, wherein said information is detectable by a capacitive touch screen comprising intersection points formed from driving electrodes and sensing electrodes. In a further aspect, the invention relates to a system comprising a touch screen which comprises intersection points formed from driving electrodes and sensing electrodes and a capacitive information carrier. Furthermore, the invention relates to a use of the capacitive information carrier and the system.
A capacitive information carrier in which information is encoded by an information pattern comprising a first and a second electrically conductive area on an electrically non-conductive substrate (1), wherein each conductive area comprises one or more sub-sections (2, 3), wherein said information is detectable by a capacitive touch screen comprising intersection points formed from driving electrodes (5) and sensing electrodes (4), wherein at least one sub-section (3) of the second electrically conductive area connects at least two sub-sections (2) of the first electrically conductive area and the at least two sub-sections (2) of the first electrically conductive area cover at least two different intersection points of the touch screen when brought into contact with said touch screen, wherein the capacitive information carrier is a self-grounding carrier due to the arrangement of the electrically conductive areas.
