How to access or get RFID UID using omnikey cardman 5421.

[Earl_M.]

I am new in RFID card reader application. i just want to know how to configure a connection using labview, my hardware is HID OMNIKEY 5421 and is connected to USB.

I used the code in this link http://forums.ni.com/t5/LabVIEW/Using-labview-how-do-I-access-the-smart-card-with-the-smart-card/td-... for me to start and check if i can get a return value.

im using a pc with OS: windows 7 64-bit and LabVIEW 2011.

hardware used with card inserted using omnikey workbench:

Hi,

From the image you have posted it seems it was a Mifare memory card which will just provide UID and not ATR (Both are different).

So what you got? Any errors? Upto scardconnect function it will work and return UID. Let us know in detail what problems you face.

I get a return code of 80100069, i look for the meaning of it and below is the description the the return code.

SCARD_W_REMOVED_CARD 0x80100069

The smart card has been removed, so further communication is not possible.

and also the return code of scardstatus it "6" which is error_invalid_handle. Even if i placed the card on top of the reader. The same values i get if i remove the card.
