Square Reader SDK

My thanks to Square for sponsoring this week at DF. You might know Square from their little white card readers, but for developers they have a suite of APIs and SDKs to help you take payments — both in-person and online. Square Reader SDK allows you to use Square hardware to take payments directly in your app. Check out their website to see their cookie-selling demo app, with complete source code to simulate everything a Girl Scout would need to sell cookies.
