An anonymous reader writes "Technology Review is running an in-depth story about the way cellphone banking is transforming the lives of many poor people in India. By enabling users to manage a legitimate bank account and finance micro-loans, cellphones are a major force of social and economic change. It's perhaps not surprising, given that despite widespread poverty, India has the world's fastest-growing cellphone market and the second largest number of cellphone users (after China). The article mentions one Indian start-up, mChek, that is thriving as a result. There's also an excellent video report."
