Online payment in Middle East and Developing Countries

I'm establishing a crowdfunding website for Start Ups. So far I figured out the only way to replace online payment would be through mobiles. I'm currently establishing this in Iraq (paypal is not available here), and I looked at a few examples of mobile payment from Nigeria and other countries, but I didn't really understand how it works.

It would be great if someone advised me to use another way of payment, or explain how the mobile payment works.

Besides that is not available in your country, Paypal and other similar services like Square, there are already other services as Flint providing a system to accept cards directly with phone's camera without requiring the dongle, which connected to the mobile reads the magnetic stripe on the card.

Another option is Bitcoin, which is also available for mobiles on Android. For any doubts there is a community of Bitcoin on stackexchange.
