TOUCHSCREEN-SENSITIVE AND TRANSPONDER READING STYLUS

摘要

The invention relates to a touchscreen-sensitive and transponder reading stylus. The aim of the invention is to provide a small touchscreen-sensitive stylus whose power requirements are low and which allows for transponder communication. The inventive stylus is characterized in that the handpiece also accommodates an RF-ID electronic system and that it comprises a tip area that tapers in at least one direction of its scanner tip. Said tip area is provided with an antenna preferably in the form of an electrical coil and is configured in such a manner that it is devoid of an electromagnetic shielding, 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.
