title: reading EMV card using PPSE and not PSE
body: <p>I'm trying to read the data off a contactless Visa Paywave card.</p>
  
  <p>For the Paywave, I have to submit a SELECT using PPSE (2PAY.SYS.DDF01) instead of PSE (1PAY.SYS.DDF01).</p>
  
  <p>The EMV book 1, section 11.3.4, table 43 only describes how to interpret the response for a successful SELECT command using PSE.  Does anyone know or can refer me to a source that shows how to process the data returned from a successful SELECT command using PPSE?</p>
  
  <p>Here's my request APDU:</p>
  
  <pre><code>00A404000e325041592e5359532e444446303100
  </code></pre>
  
  <p>Here's the response:</p>
  
  <pre><code>6F2F840E325041592E5359532E4444463031A51DBF0C1A61184F07A0000000031010500A564953412044454249548701019000
  </code></pre>
  
  <p>I understand tag <code>84</code>, tag <code>85</code>, tag <code>BF0C</code> from the response.  According to the examples for reading PSE, I should be able to just send GET PROCESSION OPTIONS (to get the AIP and AFL) with PDOL = null after this successful response as follows: <code>80A80000830000</code>. </p>
  
  <p>But request <code>80A80000830000</code> returns error code <code>6985</code> - Command not allowed; conditions of use not satisfied.</p>
  
  <p>I also tried reading all the files after successfully selecting the PPSE by traversing through every single SFI (0-30) and every single record (0-16) of each SFI.  Yes, I also did the 3 bit shift and bitwise-OR the SFI with <code>0x4</code>.  But I got no data.</p>
  
  <p>I'm stuck, any help that would point me into getting some info from my Paywave card would be appreciated!</p>
