title: How can I read the purse balance with an EMV CARD?
body: <p>I'm working with a smart card reader and I'm finding some trouble about getting the purse balance from an EMV card. I have developed software for other cards with t=0, protocol, but this time this process is killing me.</p>
  
  <p>I supposse it has to be something like :</p>
  
  <p>Select Purse balace File
  Read Record.</p>
  
  <p>I did not find this file, and then I saw in the specifications this:</p>
  
  <p>It's mandatory to:</p>
  
  <ol>
  <li>select the PSE</li>
  <li>Read Record</li>
  <li>Get processing options</li>
  <li>Read Record</li>
  <li>Get Chanllenge command</li>
  <li>Get Data command</li>
  </ol>
  
  <p>I honestly think with command 6 I will obtain what I'm looking for, the problem is that I cannot select the pse, but instead I can select the AID standard visa file.</p>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks</p>
