Abstract

Upon recognizing a loss of a first connection to a computing apparatus, such as a personal computer, a smart card reader may maintain an open session with a smart card and may associate an identity of the computing apparatus of the first connection with the open session. Some time later, the smart card reader may establish a second connection with a computing apparatus. The smart card reader may compare an identity of the computing apparatus of the second connection with the identity of the computing apparatus of the first connection. Responsive to determining that the identities do not match, the smart card reader may close the open session with the smart card. Responsive to determining that the identities do match, the smart card reader may maintain the open session with the smart card.

Claims

1. A method of facilitating communications between a computing device and a smart card reader, said smart card reader configured for communication with a smart card, said method comprising:

recognizing, during an active session with said smart card, a loss of a connection between said smart card reader and said computing device; and

subsequent to said loss, refraining from closing said active session with said smart card, thereby maintaining an open session with said smart card, and associating an identity of said computing device with said open session.

2. The method of claim 1 wherein said connection between said smart card reader and said computing device comprises a wireless connection.

3. The method of claim 2 wherein said wireless connection employs a Bluetooth communication protocol.

4. The method of claim 1 wherein said connection between said smart card reader and said computing device comprises a wired connection.

5. The method of claim 1, further comprising:

initializing a timer subsequent to said loss,

wherein said timer is associated with a configurable timeout value indicating a duration for which said smart card reader maintains said open session with said smart card.

6. The method of claim 5 wherein said timeout value is disabled.

7. The method of claim 5 wherein when said timer has exceeded said timeout value, said smart card reader closes said open session with said smart card.

8. A computing device comprising a processor adapted to execute a smart card reader service to:

recognize, during an active session with a smart card, a loss of a connection between a smart card reader configured for communication with said smart card, and said computing device; and

subsequent to said loss, refrain from closing an active session with said smart card, thereby maintaining an open session with said smart card, and associate an identity of said computing apparatus with said open session.

9. The computing device of claim 8 wherein said connection between said smart card reader and said computing device comprises a wireless connection.

10. The computing device of claim 9 wherein said wireless connection employs a Bluetooth communication protocol.

11. The computing device of claim 8 wherein said connection between said smart card reader and said computing device comprises a wired connection.

12. The computing device of claim 8 wherein said processor is further adapted to execute said smart card reader service to initialize a timer subsequent so said loss, wherein said timer is associated with a configurable timeout value indicating a duration for which said smart card reader maintains said open session with said smart card.

13. The computing device of claim 12 wherein said timeout value is disabled.

14. The computing device of claim 13 wherein when said timer has exceeded said timeout value, said smart card reader closes said open session with said smart card.

15. A computer readable medium containing computer-executable instructions that, when performed by a processor of a computing device, cause said processor to:

recognize, during an active session with a smart card, a loss of a connection between a smart card reader configured for communication with said smart card, and said computing apparatus; and

subsequent to said loss, refrain from closing said active session with said smart card, thereby maintaining an open session with said smart card, and associate an identity of said computing device with said open session.

16. The computer readable medium of claim 15 wherein said connection between said smart card reader and said computing device comprises a wireless connection.

17. The computer readable medium of claim 16 wherein said wireless connection employs a Bluetooth communication protocol.

18. The computer readable medium of claim 15 wherein said connection between said smart card reader and said computing device comprises a wired connection.

19. The computer readable medium of claim 15 wherein said computer-executable instructions, when performed by said processor, further cause said processor to initialize a timer subsequent to said loss, wherein said timer is associated with a configurable timeout value indicating a duration for which said smart card reader maintains said open session with said smart card.

20. The computer readable medium of claim 19 wherein said timeout value is disabled.

21. The computer readable medium of claim 19 wherein when said timer has exceeded said timeout value, said smart card reader closes said open session with said smart card.
