Abstract
The invention relates to a touchscreen-sensitive and transponder reading stylus. The object of the invention is to provide a small touchscreen-sensitive stylus whose power requirements are low and which allows transponder communication. The inventive stylus is characterized in that a hand-piece also accommodates an RF-ID electronic system and that it comprises a tip range that tapers in at least one direction of its scanning tip. Said tip area is provided with an antenna preferably in the form of an electric coil and is configured in such a manner that it is devoid of an electromagnetic screening, that an electromagnetic field emitted at the tapered end is substantially not attenuated and that it is suitable for the optically exact scanning of screens.
