Problems solved by technology

Unfortunately, stealing devices have become very professional looking and may now be difficult to visually identify with some sort of sensor
Some limited success may have been achieved by using video cameras to inspect surfaces of stolen devices

Embodiment Construction

[0035] Reference will be made to the drawings, in which reference numerals will be given to the various elements of the invention and in which the invention will be discussed to enable those skilled in the art to make and use the invention. It should be understood that the following description is merely exemplary of the principles of the invention and should not be taken as narrowing the appended claims.

[0036] While many embodiments of the present invention use general purpose touchpads, other capacitive sensing devices that are not touchpads may be used to achieve the same results and should be considered within the scope of the present invention. But when a touchpad is used to implement the invention, the touchpad can be dedicated to providing detection of an intrusion sensor, or used to provide both intrusion detection and touchpad functionality. Therefore, use of the term touchpad should not be construed as limiting the invention.

Abstract

Capacitive sensing electrodes may be placed in strategic locations inside, outside or inside and outside of a card reader, wherein touch sensor circuitry is then used to take mutual capacitance or self-capacitance measurements that are saved in non-volatile memory as a reference intrusion measurement that is not deleted when power is removed, wherein the reference intrusion measurement may then beused during subsequent intrusion measurements to determine if a skimming device has been disposed adjacent to the card reader, and if a skimming device is detected, appropriate action may be taken such as the automatic disabling of the card reader, the display of a message indicating that the card reader should not be used, or any other action that may prevent a financial card from being compromised.

Description

technical field [0001] The present invention generally relates to card readers. More specifically, the present invention relates to the ability to detect a skimming device attached to the exterior of a financial card reader or inserted into a slot of a financial card reader by using capacitive sensing techniques. Background technique [0002] There are several designs for capacitive sensors that can be used to achieve the objectives of the present invention. One of the existing capacitive sensor designs that can be modified to work with the present invention is the Company-made touchpads. Therefore, it is useful to examine the underlying technology to better understand how any capacitance-sensitive touchpad can be modified to work with the present invention. [0003] The company's touchpad is a mutual capacitance sensing device and an example is shown as a block diagram in FIG. 1 . In this touchpad 10 , a grid with X ( 12 ) and Y ( 14 ) electrodes and sense electrodes...
