According to the G20, 2.5 billion adults are excluded from the formal financial system. This part considers the influence of FinTech on emerging markets and the social impact that can be generated through financial technology in terms of ensuring access to financial services and products for the unbanked, i.e. democratizing finance. The cash economy is being supplemented by mobile access to digital funds. This change is not led by traditional banks but by telecoms companies who power mobile transactions. FinTech start-ups can become the engine that enables access to those in need. FinTech can help the unbanked to overcome discrimination in the provision of financial services, while decreasing friction and transaction costs for savings and payments.
