How to get this fine piece software to do something usefull?
No documentation will be found which is not grey and out of the last century.
ReinerSCT is here and connectet, The software speaks whith the cardreader but the window closes very fast und nothing, realy nothing will be changed.

Greetings

Hm, what does the output in a terminal window show in case you start KMyMoney from the command line (e.g. konsole)? Where did you get the packages from and in which version? There are at least three I can think of:

* KMyMoney
* AqBanking (incl. Gwenhywfar) and the
* Reiner SCT card driver.

I am (very) familiar with the first ones but not the card reader. And rest assured, it does something useful. At least for me, for the last 15 years or so And there is documentation. Did you check the manual?
