摘要： A method is provided for facilitating communications between a computer device and a smart card reader having an associated smart card. The computer device includes a smart card resource manager and a smart card reader service, the smart card reader service acting as a relay for commands between the smart card resource manager and the smart card reader. The method comprising the smart card reader service: (a) receiving from the smart card resource manager a first command for placing the smart card in a first state and relaying the first command to the smart card reader; (b) receiving a second command from the smart card resource manager for placing the smart card into a second state and a third command from the smart card resource manager for placing the smart card into the first state; and (c) determining if the smart card was in the first state prior to receiving the second command, and (i) if the smart card is determined to have been in the first state then forgoing relaying the second command and the third command to the smart card reader, and (ii) if the smart card is not determined to have been in the first state, then relaying the second command and the third command to the smart card reader.

摘要： Communications between a computing device and a smart card reader (SCR) configured for communication with a smart card are facilitated through the use, by the computing device, of a smart card resource manager and a smart card reader service (SCRS). The SCRS acts as a relay for commands between the smart card resource manager and the SCR. Appropriate configuration of the SCRS obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the SCR. However, upon re-establishing a previously lost connection to a SCR and determining that a communication link between a smart card and the SCR has been ended and reestablished during the loss of connection, the SCRS may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.
