Abstract

Die Erfindung betrifft ein kontaktloses Transpondersystem mit einem kontaktlosen Transponder, insbesondere einer kontaktlosen Chipkarte, einer Kopfstation, insbesondere einer Schreib-/Lesestation bzw. einer Lese-/Schreibstation, und einer Schnittstelle zur Übertragung von Information und/oder Energie zwischen dem Transponder und der Kopfstation an deren Endpunkt wenigstens eine Energie-/Sendespule (1) vorgesehen ist. Um die Fernwirkung der Energie-/Sendespule aufzuheben bzw. zumindest zu verringern, ist erfindungsgemäß vorgesehen, daß der Energie-/Sendespule (1) wenigstens eine Kompensationsspule (2, 11) zur Kompensation von Fernfeldkomponenten der Energie-/Sendespule (1) zugeordnet ist.
