Electronic circuit for chip card interfaces has communication device switched between alternate chip card interfaces with selective activation of corresponding analogue interface

摘要

The electronic circuit has a communication device (4) selectively coupled to a first or a second chip card interface (7,8) via a port transfer switch (6) and a device (9,10) for activating an analogue interface of the first or the second chip card interface dependent on the selection of one or other of the latter. Also included are Independent claims for the following: (a) a chip card terminal; (b) a method for communication with chip card interfaces; (c) a computer program product for communication with chip card interfaces
