SYSTEM AND METHOD FOR DETECTING A SMART CARD
A card reader for reading a bank card and a method of use thereof is disclosed. The card reader housing has a card entry slot where a customer inserts a bank card, either a magnetic stripe card or a chip-based smart card. A camera is mounted adjacent to the card entry slot in a position to allow an image to be taken of an upper surface of a bank card inserted into the card entry slot. A chip reader unit reads the chip-based smart card. A controller is coupled to the camera and to the chip reader unit. The controller processes an image received from the camera to determine that the inserted bank card is a chip-based smart card in a proper orientation. The controller enables the chip reader unit upon determining that the inserted bank card is a chip-based smart card in proper orientation.
1 . A card reader, comprising:
a camera mounted in a housing adjacent to a card entry slot formed in the housing, the camera mounted in position to allow an image to be taken of an upper surface of each bank card inserted into the card entry slot;
a chip reader unit for reading a chip-based smart card; and
a controller coupled to the camera to receive images therefrom and to the chip reader unit, the controller processing the images received from the camera to determine when the inserted bank card is a chip-based smart card in a proper orientation, the controller enabling the chip reader unit upon determining that the inserted bank card is a chip-based smart card in the proper orientation.
2 . The card reader of claim 1 , wherein the controller processes the image received from the camera to determine when the inserted bank card is a chip-based smart card in the proper orientation based on machine learning.
3 . The card reader of claim 1 , wherein the controller processes the image received from the camera to determine when the inserted bank card is a chip-based smart card in the proper orientation based on image processing.
4 . The card reader of claim 1 , further comprising an input read head mounted in the housing adjacent to the card entry slot, the input read head mounted in position to sense a magnetic stripe on a lower surface of the bank card inserted into the card entry slot by detecting magnetic flux therefrom.
5 . The card reader of claim 4 , wherein the controller is coupled to the input read head to receive a signal from the input read head based on whether magnetic flux could be detected from a magnetic stripe on the inserted bank card, the controller determining that the inserted bank card is a magnetic stripe card in a proper orientation upon receipt of a signal from the input read head confirming that magnetic flux was read from the inserted bank card.
6 . The card reader of claim 5 , further comprising a magnetic stripe read/write head for reading from and writing to a magnetic stripe on a magnetic stripe card inserted into the card reader.
7 . The card reader of claim 6 , wherein the controller is coupled to the magnetic stripe read/write head, the controller enabling the magnetic stripe read/write head upon determining that the inserted bank card is not a chip-based smart card in the proper orientation and that the inserted bank card is a magnetic stripe card in the proper orientation.
8 . The card reader of claim 1 , further comprising a card width detection sensor mounted in the housing adjacent to the card entry slot, the card width detection sensor providing an output signal indicating that a card inserted into the card entry slot has a width corresponding to the width of a bank card.
9 . The card reader of claim 8 , wherein the controller is coupled to the card width detection sensor and processes the image received from the camera to determine when the inserted bank card is a chip-based smart card in the proper orientation only when the output signal from the card width detection sensor indicates that the card inserted into the card entry slot has a width corresponding to the width of a bank card.
10 . The card reader of claim 5 , further comprising a card width detection sensor mounted in the housing adjacent to the card entry slot, the card width detection sensor providing an output signal indicating that a card inserted into the card entry slot has a width corresponding to the width of a bank card.
11 . The card reader of claim 10 , wherein the controller is coupled to the card width detection sensor, the controller processing the image received from the camera to determine when the inserted bank card is a chip-based smart card in the proper orientation or determining that the inserted bank card is a magnetic stripe card in the proper orientation upon receiving a signal from the input read head confirming that magnetic flux was read from the inserted bank card only when the signal from the card width detection sensor indicates that the card inserted into the card entry slot has a width corresponding to the width of a bank card.
12 . The card reader of claim 1 , wherein the controller generates an alarm signal upon determining that the image received from the camera shows that a foreign object has been inserted into card entry slot.
13 . A method of reading a bank card, comprising the steps of:
generating an image of an upper surface of a bank card inserted into a card entry slot formed in a housing of a card reader;
processing the generated image to determine when the inserted bank card is a chip-based smart card in a proper orientation;
enabling a chip reader unit upon determining that the inserted bank card is a chip-based smart card in the proper orientation; and
reading information from a chip on the inserted bank card.
14 . The method of claim 13 , wherein the image is generated by a camera mounted in the housing adjacent to the card entry slot.
15 . The method of claim 14 , wherein the generated image is processed by a controller coupled to the camera.
16 . The method of claim 13 , wherein the step of processing the generated image to determine when the inserted bank card is a chip-based smart card in the proper orientation is performed based on machine learning.
17 . The method of claim 13 , wherein the step of processing the generated image to determine when the inserted bank card is a chip-based smart card in the proper orientation is performed based on image processing.
18 . The method of claim 13 , further comprising the step of sensing a magnetic stripe on a lower surface of a bank card inserted into the card entry slot by detecting magnetic flux therefrom.
19 . The method of claim 18 , further comprising the step of determining that the inserted bank card is a magnetic stripe card in a proper orientation upon receiving a signal confirming that magnetic flux was read from the inserted bank card.
20 . The method of claim 14 , further comprising the step of generating an alarm signal upon determining that the image received from the camera shows that a foreign object has been inserted into card entry slot.
