Boku Network Services Estonia (formerly known as Fortumo) allows any merchant to set up payment processing for the web and mobile services, games or apps. Users with a mobile phone are then able to make one-click payments using Fortumo without the need for a credit card - payments are charged to their mobile operator bill instead. Fortumo payments are cross-platform and work in PC applications, web services and HTML5, Android, Windows Phone and Windows 8 apps. Fortumo supports payments through 350 mobile operators, including a number of exclusive direct carrier billing partnerships.
