I'm getting this message SCARD_W_UNRESPONSIVE_CARD when trying to do anything with a specific ACOSJ card.
I have a card reader that I'm using with multiple cards of the same type, no problems, and no problems with the other ACOSJ cards either. What does this error mean? Is the card not getting an ATR? What are the possible reasons for this and how can I fix it/debug it if I can't communicate with it?
I have this error occasionally and the only reason in my case is that the contacts of the card are not properly placed. In this case the card must be reinserted or is in general too thin. In case of a SIM this happens when the nano SIM was already broken out and is not reinserted properly again. Maybe there is also a problem with the voltage being the real underlying cause of this.
