1. Technical Field
The invention relates to a device for reading magnetic stripe cards and/or smart cards, in particular EC (electronic cash) cards and credit cards, which comprises a slot for feeding magnetic stripe card and/or smart cards in a feed direction, a fed magnetic stripe card and/or smart card being arranged in a feeding plane during feeding. Further, the invention relates to a method for preventing skimming attacks, in which a magnetic stripe card and/or smart card is fed to a device for reading magnetic stripe cards and/or smart cards, the magnetic stripe card and/or smart card being arranged in a feeding plane during feeding.
2. Discussion
In automated teller machines, POS systems, payment terminals and other devices in which magnetic stripe cards and/or smart cards, for example EC cards, credit cards or bank cards, are inserted for payment or withdrawal of cash, there is the problem that people attempt, with intent to defraud, to unauthorizedly read out the data stored on the cards and to spy out data associated with the card to thus be able to withdraw cash by means of these data in an unauthorized manner. Such attempts to spy out the data are referred to as skimming attacks.
Numerous methods are known by which one attempts to detect skimming modules that are arranged outside in front of the feeding slot for the magnetic stripe card and/or smart card. For example, the corresponding areas are monitored by means of cameras, and changes in the structure are detected.
To prevent this, recently more and more very small miniature skimming modules are inserted into the same slot into which the magnetic stripe card and/or smart card is inserted. These modules are designed such that they can read out the data of the cards, while these cards are accepted normally within the device for reading magnetic stripe card and/or smart cards.
From the document DE 10 2006 049 204 B2, it is known to insert EC cards into an automated teller machine with their longer longitudinal side first and thus transversely to the reading direction of the magnetic stripe card. In this way, it shall be prevented that skimming modules mounted on the outside of the automated teller machine can read out data when the card is drawn in. The direction of movement of the card is then changed in the automated teller machine so that now it is transported with its short side first and the magnetic stripe card can be read out during this transport via a stationary reading head.
It is an object of the invention to specify a device for reading magnetic stripe cards and/or smart cards as well as a method for preventing skimming attacks, by means of which skimming attacks carried out by miniature skimming modules inserted into the slot can be prevented reliably in an easy manner.
According to an aspect of the invention, a rotary unit for rotating an inserted magnetic stripe card and/or smart card from the feeding plane into a reading plane is provided behind the slot as viewed in the feed direction, the reading plane extending at a predetermined angle relative to the feeding plane. By means of this rotation of the magnetic stripe card and/or smart card after its feeding into a reading plane that is different from the feeding plane it is achieved that inserted miniature skimming modules which are inevitably arranged in the feeding plane cannot read out the smart card that is no longer arranged in the feeding plane. Thus, such skimming attacks are prevented reliably and securely.
In the preferred embodiment of the present application, this rotation is generally defined such that the orientation of the magnetic stripe card and/or smart card is changed in such a way that the plane defined by the magnetic stripe card and/or smart card changes. In particular, this rotation is not defined such that the orientation of the magnetic stripe card and/or smart card is changed only within a plane.
Preferably, the feeding plane and the reading plane are not identical and not parallel to each other either.
By the magnetic stripe card and/or smart card being arranged in a specific plane, it is in particular understood that it lies with its face, i.e. its front or rear side, within this plane.
The predetermined angle in particular has a value between 30° and 120°, preferably between 80° and 100°. It is particularly advantageous when the reading plane is orthogonal to the feeding plane, i.e. when the predetermined angle has a value of 90°. This means that the magnetic stripe card and/or smart card is rotated by 90° by means of the rotary unit.
The feeding plane in particular extends horizontally. In the preferred embodiment in which the reading plane is orthogonal to the feeding plane, the reading plane thus extends vertically.
The magnetic stripe card and/or smart card is in particular an EC card, a credit card or a bank card. The device for reading a magnetic stripe card and/or smart card is in particular an automated teller machine (ATM), an automatic point of sale (POS) system, an automated teller safe, a payment terminal or a reading unit that can be integrated in machines.
In a preferred embodiment, the rotary unit comprises transport elements for transporting the magnetic stripe card and/or smart card along a transport path, the transport path being formed such that the magnetic stripe card and/or smart card is rotated from the feeding plane into the reading plane during transport along the transport path. The transport path in particular has an arc-shaped section by which the rotation of the magnetic stripe card and/or smart card is caused. This arc-shaped section can in particular be shaped like a circular arc segment. Given a rotation by 90°, this circular arc segment-shaped section in particular corresponds to a quarter circle-shaped section. In this way, the magnetic stripe card and/or smart card can reliably be rotated in an easy manner.
In an alternative embodiment of the invention, the rotary unit can also be designed such that the magnetic stripe card and/or smart card is rotatably by means of the rotary unit from the feeding plane into the reading plane about a longitudinal axis of the magnetic stripe card and/or smart card, this longitudinal axis preferably being stationary during rotation. For this, the rotary unit in particular comprises at least one gripping element for gripping an inserted magnetic stripe card and/or smart card, this gripping element being adjustable by means of a drive unit preferably such that the gripped magnetic stripe card and/or smart card can be rotated by the predetermined angle. Thus, a particularly simple space-saving rotary unit is realized.
In particular, two gripping elements are provided which grip the magnetic stripe card and/or smart card on opposite sides. The two gripping elements can preferably be rotated synchronously so that the magnetic stripe card and/or smart card is rotated accordingly, without torsion forces acting thereon and any damages occurring.
In case that the magnetic stripe card and/or smart card is fed with its longitudinal side first, the gripping elements are in particular arranged such that they grip the magnetic stripe card and/or smart card at its two short sides. In particular each of the gripping elements grips the magnetic stripe card and/or smart card such that they neither contact the magnetic stripe card nor the chip in the smart card. Thus, it is guaranteed that the magnetic stripe card or the chip can be read out while the magnetic stripe card and/or smart card is still held by the gripping elements. Alternatively, when the magnetic stripe card and/or smart card is fed with one of its longitudinal sides first, the gripping elements can also be arranged at the two longitudinal sides.
It is particularly advantageous when the rotary unit rotates the magnetic stripe card and/or smart card about that one of its longitudinal axes that extends orthogonally to the feed direction. In this way, a particularly simple design of the device can be achieved. Alternatively, the rotary unit can also rotate the magnetic stripe card and/or smart card about one of its longitudinal axes that extends in the feed direction.
The rotary unit is in particular arranged directly behind the slot, as a result whereof it is guaranteed that the orientation of the card is immediately changed before a skimming module that might have been inserted can access the data. In particular, in this way also the space for skimming modules that might be inserted is minimized.
The slot is preferably dimensioned such that the magnetic stripe card and/or smart card is insertable into the slot for feeding into the device with one of its longitudinal sides first. This has the advantage that the magnetic stripe card and/or smart card is fed transversely to the reading direction of the magnetic stripe card so that a skimming module mounted in front of the slot cannot read out these data during feeding of the magnetic stripe card and/or smart card.
The device in particular has a reading unit for reading out data stored on the magnetic stripe card of the magnetic stripe card and/or smart card and/or for reading out data stored on the chip of the magnetic stripe card and/or smart card. The reading unit is in particular designed such that the magnetic stripe card and/or smart card can be read only when it is arranged in the reading plane.
In a particularly preferred embodiment, the reading unit comprises a reading head for reading the data stored on the magnetic stripe card, which reading head is movable along the magnetic stripe card of a magnetic stripe card and/or smart card arranged in the reading plane at a reading position. Thus, the magnetic stripe card can be read out without the magnetic stripe card and/or smart card having to be moved for this. This is particularly advantageous since after the rotation of the magnetic stripe card and/or smart card thus no transport within the reading plane is required.
A further aspect of the invention relates to a method for preventing skimming attacks, in which the magnetic stripe card and/or smart card is rotated after feeding so that it is arranged in a reading plane that extends at a predetermined angle relative to the feeding plane in which the magnetic stripe card was arranged during feeding. The reading out of data stored on the magnetic stripe card or the chip by means of skimming modules inserted into the slot is prevented by this method.
Further features and advantages of the invention result from the following description which explains the invention in more detail on the basis of embodiments.
In
The automated teller machine 10 comprises a slot 12 for inserting magnetic stripe cards and/or smart cards. Further, the automated teller machine 10 has a display 14 for displaying information to a user and a keyboard 16 which serves, inter alia, for the input of the PIN that is assigned to an inserted magnetic stripe card and/or smart card to thus authenticate the user. In an alternative embodiment of the invention a keyboard 16 can also be dispensed with when the display 14 is designed as a touchscreen so that the input of the PIN and of further information can be done via this touchscreen 14.
In the case of unauthorized skimming attacks, the people carrying out the skimming attack often insert a miniature skimming module into the slot 12, which skimming module is designed such that it can read out the data of a magnetic stripe card and/or smart card inserted normally into the slot. Further, by the people carrying out the skimming attack the PIN is spied out, which may take place for example by means of a camera mounted in a hidden manner or a further keyboard mounted on the actual keyboard 16. If the person carrying out the skimming attack thus knows both the data of the magnetic stripe card and/or smart card and the PIN, this person can draw money from the account associated with the magnetic stripe card and/or smart card in an unauthorized manner.
In order to prevent such skimming attacks with inserted skimming modules, the structure schematically illustrated in
According to the teachings of this invention, a rotary unit 18 for rotating a magnetic stripe card and/or smart card is provided behind the slot 12. The magnetic stripe card and/or smart card 22 is fed in a feeding plane 24 in a feed direction P1, as schematically illustrated in
In a preferred embodiment, as illustrated in
In
Referring also to
In an alternative embodiment of the invention as shown in
Further, also any other possibility for rotating the magnetic stripe card and/or smart card 22 is possible. It is only essential that the magnetic stripe card and/or smart card 22 is rotated by the predetermined angle as immediately as possible after its input.
After the magnetic stripe card and/or smart card 22 had been rotated by the predetermined angle and is thus, as shown in
By rotating the magnetic stripe card and/or smart card it is achieved that a skimming module which might be inserted via the slot 12 cannot rest on the magnetic stripe card and/or smart card 22 and thus cannot remain in contact with the chip 36 of the magnetic stripe card and/or smart card 22. Thus, the magnetic stripe card and/or smart card 22 can be read out only by the reading unit 20 and the reading out of the data by unauthorized people can be prevented reliably.
