Abstract
A card reader includes a movable upper surface platform with a lower surface platform including one or more sensors. When there is no card transaction in progress, the upper surface platform moves toward the lower surface platform and locks in place making contact with the lower surface platform. The one or more sensor indicate whether the two surfaces are in contact with one another. When the two surfaces are not in contact with one another, when the card reader is in an idle state, the card reader shuts down/disables since there is foreign object is present in the card reader's transport path, which may indicate a skimmer/shimmer was placed in the card reader.

(canceled)
A method, comprising:
- detecting, by a processor of a card reader, an idle state of the card reader;
- moving a moveable platform toward a lower surface of the card reader during the idle state;
- and
- disabling, by the processor, the card reader when a sensor on the lower surface does not report an all-clear event indicating the moveable platform is in contact with the lower surface.
A method, comprising:
- receiving, by a processor of a card reader, an event indicating the card reader has entered an idle state;
- determining, by the processor, whether a moveable platform of the card reader is in contact with a lower surface of the card reader;
- and
- disabling, by the processor, the card reader when the moveable platform is determined not to be in contact with the lower surface.
A system, comprising:
- a card reader having a lower surface and a moveable upper surface opposing the lower surface, wherein at least one sensor is located on the lower surface;
- and
- a processor configured to disable the card reader when the card reader is in an idle state and the at least one sensor does not report contact between the moveable upper surface and the lower surface.
