Approached by a Nigerian integration company after successfully delivering a project for the largest mobile operator in Africa, we built a mobile money system for a bank in Nigeria. We used an open source microfinance solution for transaction processing which we integrated with an electronic transfer agent. The provided multi-channel integration façade was connected to a USSD protocol integration platform. Moreover, we integrated the mobile, WAP, web and ATM channels.
Now we work for 4 of the 5 largest banks in Nigeria. We've built mobile banking applications used by more than 100,000 people and USSD payment solutions. All of them required direct integration with core banking systems or with a service bus.
