Smartcard reader naming

Question

I have two readers (HID OMNIKEY 5321) in system (every reader performs a different function)

reader 1 - "Smart Card Reader 0"
reader 2 - "Smart Card Reader 1"

In my program is set up that

"Smart Card Reader 0" - action 1
"Smart Card Reader 1" - action 2

but sometimes (without rebooting, perhaps lost contact)

reader 1 gets name "Smart Card Reader 1"
reader 2 gets name "Smart Card Reader 0"

and the program does not do what users need. I use SCardGetStatusChange (requires the name of the reader) in WinScard.dll

What to do? Is there a way to change the name of the reader (firmware, drivers...)? Is it possible to use the serial number of the reader?

I also looked, but no result Smartcard reader naming: when removing any reader, the name of the rest changes How are PCSC smart card reader 'friendly names' constructed?

Would have been nice if you had included the variable declarations so we know what you are sending and expecting back. I have an idea but don't want to get it wrong. – user692942 Jan 09 '15 at 15:53
Thank you for posting it, @Yuriy -- just used it in my code. – tsul Mar 05 '16 at 17:49

Maybe you should focus on the smartcard inserted in / connected to the reader rather than the reader itself and use card specific information (i.e. serial number or label) to choose the correct reader.

My application is designed for wakeboarding cable park. Each client has one card. action 1 - electronic queue, action 2 - start/stop – Yuriy Jul 07 '14 at 20:32
Different location. Reader 1 - starting area. Reader 2 - front of the screen (electronic queue) – Yuriy Jul 08 '14 at 07:36
