Maybe it is only me, but does anyone else notice a big jump in the number of merchants that are printing the entire credit card number and expiration date on receipts? Over the past 6 months I have had to educate about a dozen local merchants about the possible abuse scenarios that exist with this type of information leakage. If there Is not already some sort of law governing this policy, there should be.
I believe there's a patent on the idea of only listing four digits of a credit card. 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 () dcs nac uci edu>
