I have heard that this is just the latest way credit card companies have thought of to make money off of our concerns about our credit rating. There is no need to monitor your credit rating monthly, and your credit information is available to you free of charge.
And the credit card companies don't want fraud to happen either, because it costs them money, so they are already monitoring your account for no extra charge - they are now just trying to get you to pay them for it monthly. My ex just got a call from the bank after they noticed a "suspicious" charge for only slightly over $100. It wasn't his and they dismissed the charge, cancelled his card, and reissued him a new one all the same day that this charge happened.
I can monitor all my financial accounts daily, from the internet. I would never pay this much to have someone else do it.
