摘要：This invention relates to a method (and a corresponding terminal) of detectinga presence of a circuit extending arrangement inserted between a physical interface,connected to a terminal, and a smart card, the physical interface being adapted to receive

the smart card, the method comprising the steps of measuring at least one electricalcharacteristic of the physical interface, and determining whether a circuit extendingarrangement, changing at least one characteristic of said physical interface, is coupled tosaid physical interface on the basis said measurement. In this way, simple and efficientdetection of a tampering/spy circuit is provided.
