Uint result = SCARD.EstablishContext(SCARD.SCOPE_SYSTEM, IntPtr.Zero, IntPtr.Zero, ref hContext) The OMNIKEY 5321 is a dual interface PC-linked reader that reads/writes to both a 13.56 MHz contactless smart card and virtually any contact smart card. Public event CardPresented CardPresented Private Dictionary lastCardFound = new Dictionary() Public class ReaderList : IDisposable, IEnumerable Public delegate void CardPresented(string reader, byte cardData) Other examples I found were time-wasting and misleading, and did not work because the DllImport was wrong. The best code that I found was from SpringCard. Now that I have my code working, I would like to share so others can benefit. I recently spend too many hours searching for an complete example of how to get the ATR from and OMNIKEY proximity card. Here's the photo, if that gives you any information. How would I go about reading the UID number? Using WINSCARD.DLL in Windows I can see that I get the "ATR" data, every single byte, but the UID is apparently not present in that part.Is the "UID" number a unique number that I can rely on? I don't really care about the 447 number, all I need to know is that the information I pick from this card will uniquely identify it later, so that I can link it to the owner of the card.447 octal = 127 hexadecimal (not found).447 octal = 295 decimal (not found as BCD-type encoding).447 decimal = 1BF hexadecimal (not found).Now, here's some conversions I've considered: When using the Diagnostics application that comes with the OmniKey card reader, I get the following information: The card has the following information stamped onto it: The card has some information stamped onto it, that I would assume, in some way, is present in the card data (there is a photo of the card and reader below.) NET 3.5 program, so this is a Windows application. Standard application interfaces include PC / SC, Synchronous-API(on top of PC / SC).ĮMD suppression capabilities allow high transmission speed and full secure read support for smart cards and passports.I am trying to read information off of a smartcard, using a contact-less OmniKey 5321 card Supports contactless smart cards with up to 848 Kbps in the fastest ISO 14443 transmission mode.
