Credit card accessories for the iPhone are getting more focus nowadays, especially since Jack Dorsey’s Square iPhone payment system was introduced a while back. Now the folks over at Intuit and Mophie have come up with the Complete Credit Card Solution for iPhone, which is a $179 package that includes Mophie’s phone case that accepts credit cards, and version 3.0 of Intuit’s GoPayment app. Users will be able to quickly register for the service and have everything up and running within 15 minutes. A single account is good enough to cover 50 users, so you can even equip a modest sales team with such devices, and Intuit’s website provides plenty of information on the transactions that take place, allowing you to link it up with Intuit’s QuickBooks suite. You’ll need to also fork out $12.95 per month to use the service, not to mention per-transaction fees between $0.30 and $0.34 and also take into account the charges from 1.7 percent to 3.7 percent of the transaction. The downside of this case is that it currently only supports the iPhone 3G/3GS, though an iPhone 4 version is already in the works. It’s currently available in Apple retail stores, and will be hitting Apple’s online store pretty soon too.
