@Bilss

I’m not sure why, but waitForCardPresent(0) only works in Linux not Windows, for Windows I use these codes:

#ifdef Q_OS_WIN32
    do {
 
        rgReaderStates.szReader = &mszReaders[iList[iReader]];
        rgReaderStates.dwCurrentState = SCARD_STATE_PRESENT;
        rgReaderStates.dwEventState = SCARD_STATE_PRESENT;
 
 
        rv = SCardGetStatusChange(hContext,
                                  INFINITE,
                                  &rgReaderStates,
                                  1);
 
    } while ((rgReaderStates.dwEventState & SCARD_STATE_EMPTY) == 0);
#else
    rgReaderStates[0].szReader = &mszReaders[iList[iReader]];
    rgReaderStates[0].dwCurrentState = SCARD_STATE_PRESENT;
    rv = SCardGetStatusChange(hContext, INFINITE, rgReaderStates, 1);
#endif

As you can see, I had to use different codes for different OS. Those codes are in C++, but it’s pretty much the same for Java.

Mikael,

I have the same exception.
I’ve been looking around and found this :http://lxr.js-home.org/lxr/source/sun/security/smartcardio/TerminalImpl.java

Apparently this happens when timeout has expired and when no card is present.
Since you called waitForCardPresent(0) , it should be inifinite timeout…

I am in the same situation, have you found a solution?

Hi i have successfully run the application with ACR 122 without the line

terminal.waitForCardPresent(0);

if i have this active my reader gets an error:

javax.smartcardio.CardException: wait mismatch
        at sun.security.smartcardio.TerminalImpl.waitForCard(TerminalImpl.java:103)
        at sun.security.smartcardio.TerminalImpl.waitForCardPresent(TerminalImpl.java:116)

Hello,
I’ve runned the code. It succeeds for the UID (ends with 9000), but have problems sending the load key. As I’ve seen there is a couple of bytes that have to changed depending on the card. How do I ger the load key for my card?
Thanks
