Method and apparatus for non-contacting information transmission

DETAILED DESCRIPTION It is therefore the object of the present invention to provide an apparatus for non-contacting information transmission that has low transmission losses and is also suitable for flat data carriers.
Another object is to provide for energy transmission between the non-contacting elements and for the modification of the electronic memory of the data carrier.
These and other objects are inventively achieved by providing a capacitative coupling for at least two signal paths between a data carrier and a data reader for information transmission.
An apparatus for implementing the present method includes the data carrier having a surface fashioned with at least two planar electrodes.
The data reader has at least two planar electrodes which are brought together with the electrodes of the data carrier so that capacitors are formed which produce at least one common circuit for the data carrier and the data reader for information transmission.
The invention is not limited to the transmission of information from a data carrier to a data reader.
On the contrary, the data reader can also be fashioned as a data generator at the same time, and the data carrier, accordingly, can be fashioned for the acceptance or, respectively, modification of the information.
