Kind Thanks,
I remove authenticate(5) and (6).
But I leave it as it is for "read for verifying". I want to make sure I am doing someting right with card.
It takes a second to verify anyhow. So there is no cost.
For verification I will use new Key A. For Writing I will use new Key B. I will use writing with new Key B later in my card operation.
Thank you very much. You saved my day.
Kind Regards.
