NIMJA is a mobile Point of Sale (mPOS) app. You could think of it as your own credit card machine that has everything it needs right on your phone. The pocket sized credit card machine is capable of accepting Visa, Mastercard, and American Express cards just like most credit card machines.
Since you can't swipe credit cards on an Android phone, there are 3 options. 1. Tap a card - NIMJA is capable of inputing credit cards with just a tap on NFC enabled phones. 2. Take a picture - with a quick picture of your credit card, NIMJA can take the card number and input them into the app for you. 3. Manually input the numbers - There is always the option to type in each number. We recommend using options 1 and 2 instead because of their speediness and simplicity. But if you love the old fashioned way, there's nothing stopping you!
Merchant can now make comments and refunds from within the app.
