Abstract

A card reader (16) having a single entry slot (18) for cards (2), and an electronic control means (35) for controlling the operation of the reader (16). The reader (16) further includes a smart card reading section (26) incorporating a plurality of terminals (34,38,36) respectively adapted to read contact smart cards, inductive contactless smart cards and capacitive contactless smart cards. A pair of endless belts (28) are arranged to form a feed path (30) there between. A card (2) inserted through the entry slot (18) is received between the endless belts (18) and transported through the card reader (16) and positioned in the smart card reading section (26) so that smart card terminals (6,8 or 10) on the card (2) are located beneath corresponding smart card terminals (34,36 or 38) in the card reader (16). Data can then be read from the card (2) if the card (2) is a contact smart card, an inductive contactless smart card or a capacitive contactless smart card.

Claims

1. A card reader (16) comprising:

an entry slot (18) for cards (2);

a smart card reading section (26) including a plurality of smart card reading means (34,38,36) for reading multiple types of ISO standard smart cards, said multiple types of ISO standard smart cards including contact smart cards, capacitive contactless smart cards and inductive contactless smart cards;

transport means (28) for moving a card (2) inserted through said entry slot (18) along a path through said reader (16) and for positioning said card (2) in said smart card reading section (26); and

electronic control means (35) for;

activating said plurality of smart card reading means (34,38,36) in sequence while said card (2) is positioned in said smart card reading section (26),

determining which type of ISO standard smart card has been inserted into said reader if said card is an ISO standard smart card (16), and

implementing an appropriate communications protocol to read data from said card (2) if it is determined that said card (2) is an ISO standard smart card.

2. The card reader according to claim 1, further comprising:

a magnetic stripe read head (32) located along said path through said reader (16); and

wherein said transport means (28) moves a card (2) inserted through said entry slot (18) past said magnetic stripe read head (32), enabling data to be read from said card (2) if said card (2) is a magnetic stripe card.

3. The card reader (16) according to claim 2, wherein:

said magnetic stripe read head (32) is located between said entry slot (18) and said smart card section (26).

4. The card reader (16) according to claim 1, further comprising:

a shutter (20) positioned adjacent the entry slot, said shutter being movable between a first position preventing access by said card, and a second permitting access by said card (2) to the interior of said card reader (16);

said shutter being under the control of said electronic control means (35), and by a magnetic read head (22) which is positioned adjacent the entry slot (18), said magnetic read head generating a signal which is transmitted to said control means (35) upon detection of a magnetic stripe (4) carried by said card (2), said control means causing said shutter to retract (20) in response to said signal.

5. The card reader (16) according to claim 2, further comprising:

a shutter (20) positioned adjacent the entry slot, said shutter being movable between a first position preventing access by said card, and a second permitting access by said card (2) to the interior of said card reader (16);

said shutter being under the control of said electronic control means (35), and by a magnetic read head (22) which is positioned adjacent the entry slot (18), said magnetic read head generating a signal which is transmitted to said control means (35) upon detection of a magnetic stripe (4) carried by said card (2), said control means causing said shutter to retract (20) in response to said signal.

6. The card reader (16) according to claim 1, further comprising:

means located along said path through said reader (16) for writing data to said card (2).

7. The card reader (16) according to claim 2, further comprising:

means located along said path through said reader (16) for writing data to said card (2).

8. The card reader (16) according to claim 1, wherein:

said smart card reading means for reading capacitive contactless smart cards comprises a line of terminals (38) located between two pairs of terminals (36) which are incorporated in said smart card reading means for reading inductive contactless smart cards.

9. The card reader (16) according to claim 2, wherein:

said smart card reading means for reading capacitive contactless smart cards comprises a line of terminals (38) located between two pairs of terminals (36) which are incorporated in said smart card reading means for reading inductive contactless smart cards.

10. A method of operating a card reader (16), comprising the steps of:

receiving a card (2) within said card reader (16);

conveying said card (2) past a magnetic stripe read head (32) so as to read any data stored on a magnetic stripe (4) on said card (2);

bringing said card (12) to rest adjacent a plurality of smart card reading means (34,38,36) for reading multiple types of ISO standard smart cards, said multiple types of ISO standard smart cards including contact smart cards, capacitive contactless smart cards and inductive contactless smart cards;

sequentially activating said plurality of smart card reading means (34,38,36) in sequence while said card (2) is positioned in said smart card reading section (26),

determining which type of ISO standard smart card has been inserted into said reader if said card is an ISO standard smart card (16), and

implementing an appropriate communications protocol to read data from said card (2) if it is determined that said card (2) is an ISO standard smart card.

11. The method according to claim 10, further including the step of:

reading said magnetic stripe (4) prior to activating the smart card reading means (34,36,38) and holding the data read from said magnetic stripe (4) until said smart card reading means (34,36,38) have been activated to determine if said card (2) is a smart card.

12. The method according to claim 10, wherein said step of sequentially activating said plurality of smart card reading means comprises the steps of first activating said smart card reading means (34) for reading contact smart cards;

and second, activating said smart card reading means (36,38) for reading contactless smart cards.

13. The method according to claim 11, wherein said step of sequentially activating said plurality of smart card reading means comprises the steps of first activating said smart card reading means (34) for reading contact smart cards;
