(FORTUNE Magazine) – It's no wonder going to the ATM is nerve-racking: There's the creepy guy who stands too close, the worry of having your tie caught in the deposit slot, and a concern that even the least paranoid can't help but ponder--do ATM receipts contain sensitive information?

Not long ago you would have had reason to worry. The Federal Reserve used to require that these slips list entire account numbers as "unique identifiers" so that customers could keep track of their different accounts. But enterprising crooks figured out they could stand behind and "shoulder surf" a customer at an ATM to spy the PIN number. With an account number rescued from the trash, they could have a counterfeit ATM card made and proceed to feast on a Benjamins buffet.

Now, though, except for your bank balance (which, depending on your tax bracket, could draw a few chuckles), an ATM receipt holds no sensitive data. The Fed amended its rule in 1995, and today most of the nation's larger banks--including Citibank, Bank of America, and J.P.Morgan Chase--disclose just a few digits on their customer receipts. It's only in Mayberry-like small towns that full account numbers still show up. So chances are your money is safe. Of course, if thieves don't get it, that dastardly Dow just might.
