In retail environments, customers can pay for items or services using a payment card, such as a credit card or debit card. To facilitate such transactions, payment terminals are provided that read information from the payment card using a magnetic strip reader, a chip reader and/or a wireless reader, for example. Payment terminals also include a keypad that allows customers to enter a PIN for their card, authorize payment and request receipts. Such payment terminals are directly accessible by the customer such that the customer taps, inserts or swipes their card in the terminal and presses the keys of the keypad.
Criminals have developed sophisticated overlays that fit on top of a payment terminal and exactly mimic the appearance of the payment terminal such that when the overlay is in place, it is difficult to perceive the presence of the overlay. Once in place, the overlay can capture information provided on the payment card and can capture PIN numbers entered through the keypad. With the payment card information and the PIN number, criminals are able to access funds provided through the card.
The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solve any or all disadvantages noted in the background.
A payment terminal evaluator includes a contact structure and a card structure. The contact structure intersects a rectangular space such that part of the contact structure is within the rectangular space and part of the contact structure is outside of the rectangular space. The card structure extends from the contact structure and is positioned entirely within the rectangular space. The card structure includes a top surface, a bottom surface, a first side surface between the top surface and the bottom surface, a second side surface between the top surface and the bottom surface, a first tab defined in part by the top surface, the bottom surface and the first side surface, a second tab defined in part by the top surface, the bottom surface and the second side surface, and an opening between the first tab and the second tab.
In accordance with a further embodiment, a method of evaluating payment terminals includes inserting a first portion of a structure into a chip-reading slot of a payment terminal while keeping the first portion from contacting electrical contacts within the chip-reading slot. The payment terminal is determined to be fraudulent when a second portion of the structure contacts the payment terminal.
In accordance with a still further embodiment, a method includes inserting a card structure having a gap into a chip-reading slot of a payment terminal such that the gap is aligned with electrical contacts within the chip-reading slot. The payment terminal is determined to not be fraudulent when a free end of a contact structure extending from the card structure fails to contact the payment terminal.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter.
In the embodiments described below, a device is provided that can be used to evaluate whether a payment terminal has an overlay placed over it while protecting electrical contacts found within the payment terminal. To determine if an overlay is present, a card structure of the payment terminal evaluator is inserted into a chip reading slot of the payment terminal. If a free end of the evaluator fails to contact the payment terminal during this insertion, the payment terminal does not have an overlay placed over it. If the free end does come into contact with something during the insertion, an overlay is present. The card structure of the evaluator includes a gap or opening that avoids making contact with electrical contacts found within the chip reading slot thereby preventing the evaluator from damaging the contacts within the payment terminal.
In order to prevent damage to electrical contacts within chip reading slot 106, card structure 202 is constructed to provide an opening or gap 242 that aligns with the contacts when card structure 202 is inserted into chip reading slot 106. In particular, card structure 202 includes a base 220 that extends from vertical component 206 and, as shown in
Second tab 234 is defined by side surface 224, a front surface 237, a second inner surface 240, top surface 226 and bottom surface 228. Front surface 237 and second inner surface 240 extend between top surface 226 and bottom surface 228. Side surface 224 extends from base 220 and intersects with front surface 237 along a curved surface 239. Front surface 237 intersects with second inner surface 240, which also intersects with recess surface 230 of base 220. Although front surface 238 and recess surface 230 are shown to intersect with inner surface 240 at right angles, in other embodiments, the surfaces intersect through a respective curved surface.
Inner surfaces 236 and 240 and recess surface 230 define gap 242 so that gap 242 has a width 244 between inner surfaces 236 and 240, and a depth 246 that is measured between front surface 238 and recess surface 230.
As shown in
Lateral components 208 and 210 extend from the top of vertical component 206 in the same direction that card structure 202 extends from vertical component 206. As a result, lateral components 208 and 210 are above card structure 202 and are separated from card structure 202 by a height 270. As shown in
In order to provide uniform wall thickness and avoid warping of evaluator 200 when the evaluator is made from plastic, wells 274 and 276 are provided in lateral components 208 and 210, respectively. In addition, recesses 280, 282 and 284 are provided in the back of vertical component 206.
As shown in
Although a specific payment terminal has been shown in the embodiments described above, evaluator 200 is not limited to being used with the particular payment terminal that is shown. In addition, although a particular geometry for evaluator 200 has been shown, in other embodiments, other geometries are used. In particular, the dimensions, positions, and numbers of lateral components are changed in evaluator 200 for different payment terminals or to detect different types of overlays. In all evaluators, however, card structure 202 includes an opening or gap sufficient to avoid contact between the card structure and any electrical contacts that may be within the chip reading slot. The exact position and dimensions of the opening or gap 242 are varied depending on the location of the electrical contacts in the payment terminal that evaluator 200 is designed to work with.
Although elements have been shown or described as separate embodiments above, portions of each embodiment may be combined with all or part of other embodiments described above.
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms for implementing the claims.
