It used to be that you only had to be paranoid about credit card skimmers when using an ATM. But times have changed, and the bad guys have gotten so sophisticated that they've now created realistic but fake point of sale terminals that even print an authentic looking receipt while they're collecting your credit card number and PIN.
Discovered and exposed by Brian Krebs over on KrebsonSecurity, the new skimmers can either be set to issue a receipt, or report back a connection error message which most consumers wouldn't think twice about. And even though the skimmers can run as much as $3,000, it wouldn't take long for someone to easily make that money back if they had access to even a handful of credit cards.
