So yes, there's an actual financial incentive to do the wrong thing. A local grocery store was doing 8 digits for a while - before they went out of business. Another shows all of them - they seem to be doing well. Shredders are your friends. But don't let that stop you from complaining to the merchant in question. Don't behead the person behind the counter - but maybe ask them to relay a message to their manager. On a related note, how do you get web vendors not to store your credit card # on their hard disks longer than absolutely necessary? I trust (ssl data entry * number of orders) a lot more than a merchant's ability to stay up to date on patches until my card expires. -- Dan Stromberg DCS/NACS/UCI <strombrg@....nac.uci.edu> -------------- next part -------------- A non-text attachment was scrubbed...
