Abstract: A method for multi-factor authentication on a device with a capacitive area sensor is provided in which a device with an electrically conductive structure on a non-conductive substrate represents a first authentication factor and information for the execution of an input sequence on the device represents a second authentication factor. Authentication can be performed by means of a comparison with reference data, in accordance with the likelihood with which a signal detected by the area sensor was generated by a combination of the first and second authentication factors. A device, a system and a kit for executing the method for multi-factor authentication on a capacitive area sensor. are provided.

Abstract: The present invention relates to an information carrier comprising an electrically non-conductive substrate with an electrically conductive layer arranged as a pattern which encodes information, wherein said pattern is formed from at least one input region, at least one connecting line and at least one contact area. The information carrier is inter alia characterized in that the sub areas of the at least one input region have an area coverage in a range of 20 to 80% and/or the at least one contact area has an area coverage in a range of 5 to 80%. In further aspects, the invention relates to a use of said information carrier and a method of manufacture.
