Swipe easy on Square credit card Reader with guide 

Square Credit Card Magnetic Swipe Reader Guide
Some have problems swiping credit card on the Square magnetic reader. Most can swipe without any problems after first few swipes. For those that have difficult time swiping on the Square magnetic reader, I made a simple guide from what I had readily available. I'm sure someone can make it better, but this is a basic idea that works. I use it for my business. Thanks
