If you want an indication of how big a deal mobile money services could be for some mobile service providers, consider that M-Pesa, operated by Safaricom, now accounts for 13.3 percent of Safaricom’s total revenue.
It is estimated that up to 364 million low-income individuals globally will be utilizing mobile money by the end of 2012, which would generate $7.8 billion in revenue.
M-Pesa’s gross revenues amounted to $157 million in 2010, up 56 percent from the previous year.
In 15 African countries, more than 10 percent of adults used mobile money in 2011. Globally, there are 137 live mobile money deployments, with 95 mobile money services in the planning stages, according to CSC.
It is estimated that two billion people have a mobile phone but do not have a bank account, suggesting the size of the potential market. Perhaps half of the world’s "un-banked" people can become mobile money users.
