You've probably seen one of these doo-dads before. I remember the first time- my mind was blown at a snow cone stand, having my card processed on someone's iPhone. Here's how it works:

Square-Stand-teaser-001The Square is a mobile, wireless payment system compromised of a Square Reader, which plugs into your smart phone or iPad, and an app. The best part? It's free (almost)! When you sign up at www.SquareUp.com, you receive your Square Reader with no contract or fees. The company only charges 2.75% per individual swipe. Beautiful.

We give The Square 3 out of 5 B's. Is it totally necessary for your day-to-day? Probably not. But something so nifty is good to have on hand.
