Handler Smart Card Reader

问题:

I'm writting app connect to Smart Card reader, And I want to connect 2 app to 2 Reader:

# Detected readers (pcsc)
Nr.  Card  Features  Name
0    Yes             ACS ACR38U 00 00
1    Yes             ACS ACR38U-CCID 01 00

But, App only connects to Reader 0: ACS ACR38U 00 00. I try with IFDHandler but it is not ok. Please help me with connecting 2 apps to 2 readers 0 and 1. Thanks.

(If I understand well)

You probably need to change the second argument of the function SCardConnect() to get a different reader.

I.e. put "ACS ACR38U-CCID 01 00" here to get the second reader.

Good luck!

I use opensc-tool -l:

# Detected readers (pcsc)
Nr.  Card  Features  Name
0    Yes             ACS ACR38U 00 00
1    Yes             ACS ACR38U-CCID 01 00

Then I get Name Reader 0 ( ACS ACR38U 00 00) for func SConnect() in App 1. Name Reader 1 ( ACS ACR38U-CCID 01 00) for func SConnect() in App 2. The present, I only can handle so. If have you other handle maybe share for me?
