PayPal is entering 10 new countries this week, including Nigeria, providing online payment alternatives for consumers via mobile phones or PCs in markets often blighted by financial fraud. Rupert Keeley, the executive in charge of the EMEA region of PayPal, the payments unit of eBay Inc , said in an interview on Monday the expansion would bring the number of countries it serves to 203. Starting on Tuesday, consumers in Nigeria, which has 60 million users and has Africas largest population, along with nine other markets in sub-Saharan Africa, Eastern Europe and Latin America will be able to make payments through PayPal. PayPal has been going through a period of reinvention, refreshing many of its services to make them easier to use on mobile (phones), allowing us to expand into fast-developing markets, Keeley said.
