In the age of everything from constant Twitter updates to Wikileaks, it seems as if nothing is kept private anymore. In fact, this lack of privacy is clearly apparent within the world of credit cards. While most people would like to believe that how they spend their money is their own private information, in reality, big brother (AKA your credit card company) is always watching. That’s right; practically every purchase you make on your credit card is scrutinized by your credit issuer. This is because credit card companies are constantly searching for patterns in spending histories that might shed some light on their customers' financial stability.
