The only solution to this is going to be something like what Heartland is going to have to do - encrypt everything from the card swipe all the way to the banks on the other end. In case you have forgotten, Heartland processes about 100,000,000 credit card transactions per month and for a period of time last year, some trojans were operating that were harvesting the magnetic tracks of swiped cards. The trojans hid on the hard drive, and until auditors started looking at the temp files on the drives (and matching what created the temp filess) the stuff hidden in unallocated drive areas weren't found. http://www.storefrontbacktalk.com/securityfraud/heartlands-new-encryption-strategy-let-em-in-but-limit-how-much-they-can-get/ http://www.storefrontbacktalk.com/securityfraud/heartlands-n... http://www.storefrontbacktalk.com/securityfraud/heartland-sniffer-hid-in-unallocated-portion-of-disk/ http://www.storefrontbacktalk.com/securityfraud/heartland-sn...
