title: Send APDU command to card through HID OMNIKEY 5427 CK
body: <p>I'm trying to pass though APDUs command via HID OMNIKEY 5427 CK to operate MIFARE Card ie. Ultralight C card, on the Windows 10 x64 OS environment using WinSCard.dll. (I'm under NXP NDA and have full access t their documents)</p>
  
  <p>I tried to find information online for days now. Seem like no published document for this model except the 2pages brochure.</p>
  
  <p>The simple command like GetUID (FFCA000000) is OK, I can get back the actual card UID.</p>
  
  <p>But for 'Authentication with Card', reference document from HID 5421 model said I should start with OpenGenericSession (FFA0000703010001), I tried that and reader always replied with 6D00h (error) </p>
  
  <p>I tried send Authentication command directly '1Ah+00h' (FFA00005080100F30000641A0000) the reader also always replied with error code.</p>
  
  <p>I've experience with HID 5421 model and it quite straight forward, not sure why this 5427 is unlike its sibling.</p>
  
  <p>And yes, I contacted HID support. No luck. No useful information I could get from them. </p>
  
  <p>If any one have idea or have 5427 software development guide please help. I'm pulling my hair for almost a week by now.</p>
