Moving toward universal access to financial services is within reach, thanks to new technologies, transformative business models, and ambitious reforms. Instruments such as e-money accounts and mobile accounts, along with debit cards and low-cost traditional bank accounts, can significantly increase financial access for those who are excluded. Bringing e-Money to the Poor: Successes and Failures examines the lessons of success from four country case studies of "gazelles"―Kenya, South Africa, Sri Lanka, and Thailand―that leapt from limitation to innovation by successfully enabling the deployment of e-money technology. These countries have thereby transformed the landscape of financial access to their poor. In addition, two country case studies (Maldives and the Philippines) yield lessons learned from constraints that stalled e-money deployments. Because technology is not a silver bullet, the case studies also explore other strategic elements that need to be in place for a country to expand access to financial services through digital technology.
