title: JavaCard T=0 handing of case 2 APDUs (0x61XX (GET RESPONSE) vs 0x6CXX)
body: <p>I have tested several javacards (Feitian D11CR, Infineon JTOP, G&amp;D Smart Cafe) over T=0 and here is what I have observed.</p>
  
  <p>If applet returns some data in case 4 APDU, the JCRE signals with SW 0x61XX that there is data available which terminal should retrieve using GET RESPONSE APDU.</p>
  
  <p>However, if applet returns some data in case 2 APDU and Le does not match number of bytes to be returned, JCRE signals with error SW 0x6CXX, instructing that the same C-APDU has to be resent with correct Le.</p>
  
  <p>For legacy reasons there are terminals who know how to handle 0x61XX, but fail to handle 0x6CXX response. Is there a way how to force JCRE to handle case 2 APDUs using 0x61XX (GET RESPONSE) method?</p>
