<p class="MsoNormal">We have two problems/not understandings:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> 1. reading more than one card at the same time<o:p></o:p></p>
<p class="MsoNormal"> 2. issuing a PWD_AUTH command to a connected card<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It is my understanding that to read a second card that is within range of a cardreader it is necessary to issue a HLTA command to the card. The HLTA is a low level card command and I have not been able to find out how to pass the card command
through pcsc to the card.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The PWD_AUTH command is also a low level card command and falls into the same issue of not knowing how to pass commands through to the card.<o:p></o:p></p>
