It's easy to forget now but, when credit cards first came on to the scene, they suffered a bad reputation, as poor security measures allowed nefarious clerks and larger-scale operators to clone and defraud accounts.

"We're not going to make it go away, because criminals exist and they try to exploit any problem," Tim Cadogan tells Beet.TV in this video interview. "But we think we're well on the path to managing the problem.
"We all use credit cards, there is fraud, but the companies that operate the cards ... do a really good job of managing and mitigating the fraud."
