Abstract
Devices, systems and methods for detecting skimming devices are provided. The present disclosure provides for a card reader assembly including a face plate having a slot for receiving a card in a direction of entry into the slot; an array of infrared proximity detectors disposed on the face plate; and a controller configured to selectively activate the array of infrared proximity detectors to determine if an object, for example, a skimming device, is placed over the slot of the face plate.
Claims21
A card reader assembly comprising:
- a housing having a slot disposed on a face plate, the slot for receiving a card in a direction of entry into the slot;
- and
- an array of at least two light emitters and at least two light sensors configured to detect an object placed over the slot,
- wherein a first light sensor is arranged to sense reflected light originating from a first light emitter and to sense light received by a direct path originating from a second light emitter and a second light sensor is arranged to sense reflected light originating from the second light emitter and to sense light received by a direct path originating from the first light emitter.

- a housing having a slot disposed on a face plate, the slot for receiving a card in a direction of entry into the slot;
- and
- an array of at least two light emitters and at least two light sensors configured to detect an object placed over the slot,
- wherein a first light sensor is arranged to sense reflected light originating from a first light emitter and to sense light received by a direct path originating from a second light emitter and at least one second light sensor is arranged to sense reflected light originating from at least one third light emitter and to sense light received by a direct path originating from at least one fourth light emitter.

A card reader assembly comprising:
- a face plate including a slot for receiving a card in a direction of entry into the slot;
- an array of at least two light emitters and at least two light sensors disposed about the slot;
- and
- a controller configured to selectively activate the array of the at least two light emitters and the at least two light sensors to determine if an object is placed over the slot of the face plate, wherein the controller determines if an object is placed over the slot based on sensing reflected light and sensing light received by a direct path.
