Square is a new financial service that allows you to charge credit cards on your iPhone or iPad and the whole idea is really quite brilliant. At first blush, you might not understand why you would want to collect credit card payments if you use PayPal or some other online banking service — but if you think about your work day and how you interact with others in a business and personal sense — Square is giving you a cash register in the palm of your hand to facilitate credit card transactions just as if you had a storefront location. After verifying your vitals on the Square website, you can begin accepting credit card transactions on your iOS device. You mange your account online. Each week, Square will deposit up to $1,000.00USD into your bank account. Square’s vig for swiped credit cards is 2.75% +15 cents and 3.5% + 15 cents for keyed-in credit cards.
