At a warehouse in New Jersey, 6,000 used copy machines sit ready to be sold. CBS News chief investigative correspondent Armen Keteyian reports almost every one of them holds a secret.

Nearly every digital copier built since 2002 contains a hard drive – like the one on your personal computer – storing an image of every document copied, scanned, or emailed by the machine.

In the process, it’s turned an office staple into a digital time-bomb packed with highly-personal or sensitive data.

If you’re in the identity theft business it seems this would be a pot of gold.
