First Claim
1. A method of facilitating communication with a smart card via a smart card reader, said method comprising:
- receiving a first command destined for said smart card;
determining that said first command has a first type;
sending said first command to said smart card reader;
subsequently to receiving said first command destined for said smart card, receiving a second command destined for said smart card;
determining that said second command has a second type that differs from said first type;
subsequently to receiving said second command destined for said smart card, receiving a third command destined for said smart card;
determining that said third command has said first type;
subsequently to receiving said third command destined for said smart card, receiving a fourth command destined for said smart card;
determining that said fourth command has a third type that differs from said first type and from said second type;

Abstract
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.
