Description
BACKGROUND OF THE INVENTION

The present invention relates to a card reader, and particularly to a housing for a self-service terminal card reader.


Secure access to a self-service terminal, such as an Automated Teller Machine (ATM) is commonly provided by identification card and personal identification number (PIN) combinations. However, this can be compromised if the card details and the PIN are obtained by a third party. One of the most common ways in which this is achieved is by placing a false reader or means of capturing the card over the card slot housing on the ATM fascia.


In one embodiment the card is then read and returned to the user, the information from the card now being accessible to the third part, who can then replicate the card. Alternatively, the card is jammed in the card reader and when the authorized user leaves the ATM to complain the third party retrieves the user's own card.


In either embodiment, the third party will watch the authorized user attempting to enter a PIN number into the ATM. Hence, the third party will now have both the user's PIN and either the user's own card or a copy card containing the same information as the user's own card. The third part can then access the user's account.

DETAILED DESCRIPTION

Reference is now made to FIGS. 1 and 2, which show a self-service terminal 10 in the form of an automated teller machine (ATM) including a card reader slot 20 in accordance with the invention. The ATM 10 has a chassis 14 to which is pivotably coupled a plastic fascia 16 covering an upper portion of the chassis 14. A door 18 is hingably coupled to a lower portion of the chassis 14. When the fascia 16 is hinged open and the door 18 is swung open, an operator can gain access to modules located within the ATM 10.


The fascia 16 provides a user interface to allow a user to interact with the ATM 10. In particular, the fascia 16 has apertures aligning with modules mounted in the chassis 14 when the fascia 16 is pivoted to the closed position. The fascia 16 defines the card reader slot 20 aligning with a card reader module 22 mounted within the chassis 14; a receipt printer slot 24 aligning with a receipt printer module 26 mounted within the chassis 14; a display aperture 28 aligning with a combined display 30 and associated function display keys (FDKs) 34 mounted as a module within the chassis 14; a dispenser slot 36 aligning with a dispenser module 38 mounted within the chassis 14; and a deposit aperture 40 aligning with a deposit module 42 mounted within the chassis 14.


The fascia 16 also includes an encrypting keypad 50 mounted on a shelf portion 52 extending outwardly from beneath the display aperture 28. The encrypting keypad 50 also receives input from the FDKs 34.


A biometric module 12 is mounted in the shelf portion 52 and includes (i.) a sensor 56 for receiving a human finger and for capturing fingerprint details, and (ii.) an interface 58 for encrypting and relaying a captured fingerprint image. The sensor 56 protrudes through an aperture in the shelf portion 52, and the interface 58 is mounted behind the shelf portion 52. The biometric sensor 56 is a Fingerloc (trade mark) AF-S2 fingerprint sensor, available from Authentec, Inc., P.O. Box 2719, Melbourne, Fla. 32902-2719, U.S.A.


As illustrated in FIG. 2, internally, the ATM 10 also includes a journal printer module 60 for creating a record of every transaction executed by the ATM 10, a network connection module 64 for accessing a remote authorization system (not shown), and a controller module 66 (in the form of a PC core) for controlling the operation of the ATM 10, including the operation of the modules.


The controller 66 comprises a BIOS 70 stored in non-volatile memory, a microprocessor 72, associated main memory 74, storage space 76 in the form of a magnetic disk drive, and a display controller 78 in the form of a graphics card.


The display module 30 is connected to the controller module 66 via the graphics card 78 installed in the controller module 66. The other ATM modules (12, 22, 26, 34, 38, 42, and 50) are connected to the ATM controller 66 via a device bus 86 and one or more internal controller buses 88.


In use, the main memory 74 is loaded with an ATM operating system kernel 92, an ATM application 94, and a biometric capture object 96. As is well known in the art, the operating system kernel 92 is responsible for memory, process, task, and disk management. The ATM application 94 is responsible for controlling the operation of the ATM 10. In particular, the ATM application 94 provides the sequence of screens used in each transaction (referred to as the transaction flow); monitors the condition of each module within the ATM (state of health monitoring); and obtains authorization for transactions from a remote transaction authorization server (not shown).


The term “screen” is used herein to denote the graphics, text, controls (such as menu options), and such like, that are presented on an SST display; the term “screen” as used herein does not refer to the hardware (that is, the display) that presents the graphics, text, controls, and such like. Typically, when a transaction is being entered at an SST, a series of screens are presented in succession on the SST display, the next screen displayed being dependent on a user entry or activity relating to the current screen. For example, a first screen may request a user to insert a card; once a card has been inserted a second screen may invite the user to enter his/her PIN; once the final digit of the PIN has been entered, a third screen may invite the user to select a transaction; and so on.



FIG. 3 illustrates the housing of a card reader module 22 in accordance with the present invention in more detail.


The card reader module 22 has a housing 100 or mouth arranged for attachment to or incorporation in self-service terminal fascia 16. The housing 100 has a card entry slot 20 for receiving a card to be scanned. The housing is at least partially transparent, with a transparent portion 102. The housing also has an internal security marking 104, which is visible through the transparent portion 102 of the housing 100.


Significantly, if for whatever reason, for example the attachment of a skimming device to the front of the fascia 16, the mark was not visible then the user would have a visual indication that the device had been compromised.


The dimensions of security can be enhanced through the shape of the feature (stop fixing of foreign objects), color (unique, difficult to match), illumination (any skimming device would also have to incorporate illumination) and the security mark itself.


Sensors (not shown) in the terminal arranged to detect the presence of added on features. If this occurs the processor 72 is arranged to alter the appearance of the security marking 104. In this case the visible appearance of the security marking 104 is altered to indicate to the user that the device may have been compromised. For example, the internal illumination of the housing may be changed from green to red.


Various modifications may be made to the above-described embodiments within the scope of the present invention, for example, different colors may be used.
