Card reader, smart card and method for processing a transaction
A card reader ( 100 ) for reading a smart card ( 200 ), the card reader ( 100 ) comprising: an antenna ( 160 ) for making a wireless connection with a smart card; and a card detector, for determining a location of the smart card ( 200 ) relative to the antenna ( 160 ); and wherein the card reader ( 100 ) has a processor ( 180 ) configured to provide communication with the smart card and to allow or provide a first wireless communication when the card ( 200 ) is determined to be at a first location ( 110 ) of the card reader and to provide a second wireless communication when the card is determined to be at a second, different, location ( 120 ) of the card reader ( 100 ).
1. A card reader device, comprising:
an antenna for making a wireless connection with a smart card; and
a card detector, for determining a location of the smart card relative to the antenna; and
wherein the card reader has a processor configured to provide communication with the smart card and to allow a first wireless communication when the card is determined to be at a first location of the card reader and to provide a second, different, wireless communication when the card is determined to be at a second, different, location of the card reader.
2. A card reader device according to claim 1 , further comprising:
a first communication zone, comprising a card receiving and holding station; and
a second communication zone, comprising a card contactless station, and wherein the card detector is configured to determine whether the smart card is within the first communication zone or the second communication zone,
wherein the first and second communication zones comprising the first and second locations of the card reader.
3. A card reader device according to claim 2 wherein the card detector is configured to detect whether the smart card is in the first communication zone or not.
4. A card reader device according to claim 2 , wherein the card receiving and holding station is configured to hold the card in a fixed position relative to the antenna, and wherein the card reader is adapted to accommodate cards of different thicknesses and to be able to communicate wirelessly with cards of different thicknesses when they are in the card receiving and holding station.
5. A card reader device according to claim 1 , wherein the card detector comprises a switch in the card receiving and holding station, or at the first location of the card reader, and wherein the switch is triggered by insertion of a card into the card receiving and holding station, or by positioning the card at the first location of the card reader.
6. A card reader device according to claim 1 , wherein the card reader is configured to provide communication of larger data transfers or longer duration between the card reader and the smart card when the card is in the first communication zone, or at the first location of the card reader, than when it is in the second communication zone, or at the second location of the card reader.
7. A card reader device according to claim 1 , wherein the card reader comprises no more than one antenna for communicating with a smart card.
8. A method of communication by a smart card, the method comprising:
receiving a signal from a card reader;
determining which one of a number of different wireless communication positions relative to the card reader the card is positioned at, using the received signal;
determining a wireless communication in dependence on the determined position; and
receiving the wireless communication from the card reader.
9. A method according to claim 8 , wherein the smart card comprises a memory containing a first set of instructions and a second set of instructions, wherein the first set of instructions, when executed, provides a first communication and the second set of instructions, when executed, provides a second communication.
10. A method according to claim 8 , the smart card comprising a sensor or electrical contact for receiving the signal from the card reader.
11. The method of claim 10 further comprising:
enabling a first set of functionalities between the smart card and the card reader upon the determination that the card is in the first communication zone.
12. The method of claim 11 further comprising:
disabling a second set of functionalities between the smart card and the card reader upon the determination that the card is in the first communication zone.
13. A method of processing a transaction, the method comprising:
determining a location of a smart card relative to an antenna of a card reader; and
providing a first wireless communication when the card is determined to be at a first communication zone; and
providing a second wireless communication when the card is determined to be at a second communication zone.
14. The method of claim 11 , wherein the first communication zone includes a card receiving and holding station.
15. The method of claim 14 , wherein the second communication zone includes a card contactless station.
