If you're thinking about using your credit card as a purchasing tool to improve your putting, then you are terribly wrong. And by using it, we mean as an alignment tool when you practice your putting game. Your credit card is small but it can give you a lots of help in aligning the golf ball; just simply replace the ball with your card so that one side is flush with the putter face. After that, just check from behind to see if it has good alignment and if not, then recalibration is that easy.
