Thanks for the reply. Yes totally agree, however, one of my card authentication is failing with basic code changes of default values itself.
Where it worked for the first time, later its consistently failing..
However, I shall try again on a new card. But still unable to understand, why authentication of PICC is failing on this card, since I have not yet changed the key, Also used the sample code of TapLinux v1.7 only with 2k3des default.
