Abstract
In the information transfer method the information (I) is collected in the memory (55) of a pointing pen (51). A selected point on the display (43) is pressed with the tip of the pen (51), whereby a frequency change of the resonant circuit (42/52) indicates the contact, and a change in the resonance signal'"'"'s strength in the receiving circuit determines the position of the pen. Then the oscillation of a second resonant circuit (43/53) is modulated with the information (I) in the memory. The received and demodulated (47) and possibly otherwise processed (48) signal is then presented on the display (43). With this method the user can transfer scanned information directly to the display of a pen computer or a mobile phone for further processing.
