Patent Images
1. A card reader device for managing access to a memory card by a plurality of accessing devices, the card reader device comprising:
- a processor;
a wireless communication interface responsive to the processor for communicating with the plurality of accessing devices; and
a memory card interface for enabling communication between the processor and the memory card;
wherein, when at least a first secure session is open between at least a first accessing device and the memory card on a first channel, and the card reader device receives an open session command from a second accessing device, the processor is configured to;
determine whether a second channel is available to support a second secure session contemporaneously with at least the first secure session,if the second channel is unavailable, determine all secure sessions established with the memory card, provide a list identifying accessing devices corresponding to the all secure sessions to the second accessing device for display in a user interface of the second accessing device, prompt for a selection of an accessing device identified in the list, and terminate a secure session of the selected accessing device in response to the selection.

12. A method of managing communication between a memory card and a plurality of accessing devices when at least a first secure session is established, the plurality of accessing devices comprising at least a first accessing device and a second accessing device, the first secure session being established between the memory card and the first accessing device on a first channel, the method comprising:
-
receiving, at a card reader device in communication with the memory card, an open session command from the second accessing device to open a second secure session with the memory card; determining whether a second channel is available to support the second secure session with the second accessing device contemporaneously with at least the first secure session; if the second channel is unavailable, determining all secure sessions established with the memory card, providing a list identifying accessing devices corresponding to the all secure sessions to the second accessing device for display in a user interface of the second accessing device, prompting for a selection of an accessing device identified in the list, and terminating a secure session of the selected accessing device in response to the selection. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A computer readable storage medium storing program instructions which, when executed by a processor on a smart card reader, cause the processor to manage communication between a memory card and a plurality of accessing devices when at least a first secure session is established, the plurality of accessing devices comprising at least a first accessing device and a second accessing device, the first secure session being established between the memory card and the first accessing device on a first channel, wherein the processor is configured to:
-
receive, at the card reader device in communication with the memory card, an open session command from the second accessing device to open a second secure session with the memory card; determine whether a second channel is available to support the second secure session with the second accessing device contemporaneously with at least the first secure session; if the second channel is unavailable, determine all secure sessions established with the memory card, provide a list identifying accessing devices corresponding to the all secure sessions to the second accessing device for display in a user interface of the second accessing device, prompt for a selection of an accessing device identified in the list, and terminate a secure session of the selected accessing device in response to the selection.

20. A card reader device for managing access to a memory card by a plurality of accessing devices when at least a first secure session is established, the plurality of accessing devices comprising at least a first accessing device and a second accessing device, the first secure session being established between the memory card and the first accessing device on a first channel, the card reader device comprising:
-
means for receiving, at a card reader device in communication with the memory card, an open session command from the second accessing device to open a second secure session with the memory card; means for determining whether a second channel is available to support the second secure session with the second accessing device contemporaneously with at least the first secure session; if the second channel is unavailable, means for determining all secure sessions established with the memory card, means for providing a list identifying accessing devices corresponding to the all secure sessions to the second accessing device for display in a user interface of the second accessing device, means for prompting for a selection of an accessing device identified in the list, and means for terminating a secure session of the selected accessing device in response to the selection.
