“How crazy would I have to make my signature before someone would actually notice? In my lifetime, I have made nearly 15,000 credit card transactions. I purchase almost everything on plastic. What bugs me about credit card transactions is the signing. Who checks the signature? Nobody checks the signature. Credit card signatures are a useless mechanism designed to make you feel safe, like airport security checks. So my question was, how crazy would I have to make my signature before someone would actually notice?”
