Abstract
Communications between a computing device and a smart card reader 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. The smart card reader service acts as a relay for commands between the smart card resource manager and the smart card reader. Appropriate configuration of the smart card reader service obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the smart card reader. However, upon re-establishing a previously lost connection to a smart card reader and determining that a communication link between a smart card and the smart card reader has been ended and reestablished during the loss of connection, the smart card reader service may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.
