Access to traditional financial services, such as deposit-taking accounts and automatic teller machines (ATMs), in developing countries has expanded in recent years. Since 2004 the number of ATMs per 100,000 adults has more than doubled, to around 22 (compared with over 70 in rich countries). Russia and Brazil have more ATMs relative to their population than other emerging markets, but according to a World Bank survey less than 2% of adults there used a mobile phone to receive money. Mobile payments are a substitute for traditional banking. In Kenya, where there are 2,381 ATMs (less than ten for every 100,000 adults), over two-thirds of people use mobile money.
