You wouldn't believe the complexity of the systems and the security that's in place. But there is one thing that can undermine even that - an inside job. No matter of digital security can protect a company if someone inside the company with secure access decides to "break in." There is no "break in" - because they're already inside.
That's a good point, Wayne. No system is hacker-proof, but an inside job is easier by far.
I generally use my debit card for purchases but since it's been potentially compromised twice in the past 12 months, I think I'm going to use my credit card now.
