    • A command destined for a smart card is received. If the command is of a state-altering type that places the smart card in a known state, it is relayed to a smart card reader unless the smart card is currently in the known state. If the command is a POWER OFF command, it is relayed to the smart card reader unless (i) the smart card is currently in the known state and (ii) within a predetermined time from receiving the command, a subsequent command of the state-altering type that places the smart card in the known state is received. If the command is not a POWER OFF command and is not of the state-altering type that places the smart card in the known state, it is relayed to the smart card reader. The command is discarded if not relayed to the smart card reader.
    • 接收到发往智能卡的命令。 如果该命令是将智能卡置于已知状态的状态改变类型,则将其转发到智能卡读卡器,除非智能卡当前处于已知状态。 如果命令是POWER OFF命令,则将其中继到智能卡读卡器,除非(i)智能卡当前处于已知状态,并且(ii)在接收到该命令的预定时间内, 收到将智能卡置于已知状态的更改类型。 如果命令不是POWER OFF命令,并且不是将智能卡置于已知状态的状态改变类型,则将其中继到智能卡读卡器。 如果不传送到智能卡读卡器,则该命令被丢弃。

    • 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.
    • 提供了一种用于促进计算机设备和具有相关联的智能卡的智能卡读卡器之间的通信的方法。 计算机设备包括智能卡资源管理器和智能卡读取器服务,智能卡读取器服务充当智能卡资源管理器和智能卡读卡器之间的命令的中继器。 该方法包括智能卡阅读器服务:(a)从智能卡资源管理器接收用于将智能卡置于第一状态并将第一命令中继到智能卡读卡器的第一命令; (b)从智能卡资源管理器接收用于将智能卡置于第二状态的第二命令和来自智能卡资源管理器的用于将智能卡置于第一状态的第三命令; 和(c)在接收到第二命令之前确定智能卡是否处于第一状态,以及(i)如果智能卡被确定为处于第一状态,然后中继第二命令和第三命令到 智能卡读卡器,以及(ii)如果智能卡未被确定为处于第一状态,则将第二命令和第三命令中继到智能卡读卡器。
