Title: Chipkarte mit einer kontaktschnittstelle und einer kontaktlosen schnittstelle
Inventor: HOFMANN HARALD
IPC: G06K19/07
Filed: 2000-11-13
Abstract: Bei Chipkarten mit einer Kontaktschnittstelle und einer kontaktlosen Schnittstelle ist ein gleichzeitiger Betrieb beider Schnittstellen nicht möglich; vielmher kann nur eine der beiden Schnittstellen betrieben werden. Um bei einer Chipkarte mit einer Kontaktschnittstelle (KI) und einer kontaktlosen Schnittstelle (KLI) beide Schnittstellen (KI, KLI) gleichzeitig zur Datenübertragung betreiben zu können, ist die Kontaktschnittstelle (KI) über eine erste Datenleitung (DL1) und die kontaktlose Schnittstelle (KLI) über eine zweite Datenleitung (DL2) mit einer logischen Schaltung (MC) verbunden. In einer oder in beiden Datenleitungen (DL1, DL2) kann je ein steuerbarer Schalter (S1, S2) vorgesehen sein, der von der logischen Schaltung (MC) angesteuert wird, die vorzugsweise als Microcontroller oder Microprozessor ausgeführt ist. Aus dem von der Kontaktschnittstelle (KI) gelieferten Takt (CL1) und dem von der kontaktlosen Schnittstelle (KLI) gelieferten Takt (CL2) kann beispielsweise durch disjunktive Verknüpfung in einem ODER-Gatter (O) der Takt (CL) für den Mikrocontroller bzw. den Mikroprozessor (MC) erzeugt werden. Die erfindungsgemäße Chipkarte lässt sich in vorteilhafter Weise als elektronische Geldbörse (EG) mit einem Kontostandanzeigegerät (AZ) realisieren.
