ABSTRACT:
An integrated circuit card including one or more integrated circuit elements interacts with a lever extending into a card-receiving receptacle in electronic apparatus for verifying correct insertion and opening a sliding shutter in the card. The integrated circuit elements are enclosed in a case having an opening for exposing a contact pattern that connects the integrated circuit elements to the electronic apparatus. The shutter is biased toward a closed position in which a forward surface covers the contact area. An inclined chamfer on a forward section of the case interacts with the lever to limit insertion to only one orientation of the case. By providing a tab on the rear of the shutter that extends from the case on the same side as the chamfer, the lever initially verifies correct insertion and subsequently engages the tab to drive the shutter to an open position exposing the contact pattern to the electronic apparatus.
