1. If you have not done so already, download Swipe. You can do so by going to: http://appninjas.com/swipeapp (opens iTunes)

2. Open Swipe on your phone. Click “Settings” at the top. Then click “Gateway”. Click the Gateway button at top and select NMI gateway. You will be using a computer to set up your account, which makes things very easy. Now click “Guided Setup” and follow the instructions on your iPhone screen. When it tells you to go to a URL and enter a Device ID, please use a computer and not your iPhone’s web browser. If you don’t have access to a computer or your phone does not have an internet connection, click Manual Setup instead.

3. You must turn test mode off in NMI before you can process transactions: Go to NMI control panel, log in, turn test mode off.

4. Guided Setup will ask for a Username and Password. You can find these in the NMI control panel.

5. Enter this data into the Guided Setup window and click “Send to iPhone”. After this step is complete, you’ll be able to process credit cards with Swipe!


Please remember to rate Swipe in the App Store. It helps us a lot!
