Anyone who has sold any Merch at a concert in the past few years knows the pain of kids wishing they could buy your merch with their parents credit card, but you have no way of charging them for it. Maybe, you’re doing a recording session and are no where near an ATM for your client to pay you, so you are left high and dry without payment. Those days are now over! You can now run a Credit/Debit Card on any 3G/Wi-Fi/Edge network! If you have an iPhone you can now use a new iPhone App called Innerfence to run these transactions. The App is a steep $49.99, though when you sign up with Authorize.net you get a $49.99 iTunes Gift Certificate as a rebate (till 4/30)! Authorize.net is who you will be dealing with as far as getting paid for your transactions. They charge a $25.00 a month merchants fee as well as the standard merchant percentages. This is not a solution if you think you may sell 1 T-shirt a month via Credit Card but a great solution to opening up the world of concertgoers spending money they do not have! BTW So far, the reviews in the App Store are flawless!
