Abstract:
1. A smart card reader (SCR) for managing concurrent access to a smart card by a plurality of accessing devices, the SCR comprising: a processor configured to provide a channel manager interfacing with the smart card; a communication subsystem responsive to the channel manager for communicating with the plurality of accessing devices; and wherein, when the channel manager receives a first command from a first accessing device and a second command from a second accessing device, and a first session is open on a first channel between the first accessing device and the smart card and a second session is open on a second channel between the second accessing device and the smart card, the channel manager is configured to prioritize the second command relative to the first command, and wherein the channel manager is further configured to: receive data units from the second accessing device intended for transmission to the smart card on the first channel; identify a channel identifier within the data units received from the second accessing device, the channel identifier identifying the first channel; and modify the channel identifier within the data units to identify the second channel, in order to indicate that the data units are intended for transmission to the smart card over the second channel.
