I just wanted to give everyone a heads up about SquareUp (https://squareup.com/). This would be a good thing for vendors who do Trade Shows, or allow customers to pick up, in-person. You DO need to own/use an iOS/Android device in order to use this service. You download the App from the App Store/Andriod Market, and the App allows you to swipe or enter credit card numbers, take a picture of what it is you're selling, and email/text your customer a receipt. Basically you sign up for SquareUp, and they send you a free credit card reader. (you can also buy one for $10 at the Apple store, and you get the $10 back as soon as you get your account setup, making the card reader free) There are NO signup fee's, or Monthly fee's. You pay 2.9% for swiped transactions, and 3.5% + 15¢ per transaction if you manually enter the credit card number. SquareUp is LEGIT, I do not work for them, It is owned/founded by the CEO of Twitter. Thought i'd share this info because it's so convenient to have while out on the go! John
