The described embodiments relate generally to devices, methods and systems for managing access to a memory card, such as a smart card, by a plurality of accessing devices. Certain embodiments relate to a smart card reader for managing concurrent access to a smart card, wherein when a channel manager receives a close session request from a first accessing device, and a first session is open on a first channel for the first accessing device and a second session is open on a second channel for a second accessing device, the channel manager is configured to: issue a close channel command to the smart card to close the second channel; issue the close session request from the first accessing device to the smart card; and issue a further session request to the smart card to re-open the first channel, and continue the second session on the re-opened first channel.
