Credit/Debit Card Security

[sf_mail_sbm () yahoo com]

Hi List,
Although Credit Card/Debit card operations are based on IT infrstructure, I have rarely seen discussion on the subject 
in Security newsgroup... 
Are there any forums that discuss about this issue? if anyone has any interesting link please share it with us... Card 
fraud has direct financial implication and has a high impact on reputational risk
Thanking you all for your feedback
