The UK-based Mobile Money Network, which is behind the Simply Tap mobile shopping app, says Visa Europe is planning to take a 15% stake in its business. Visa Europe will join the MNN’s three founders: Monitise, Best Buy Europe and Charles Dunstone. The two businesses aim to implement a number of m-commerce initiatives in the UK in 2012.

Peter Ayliffe, Chief Executive of Visa Europe, said “This agreement is another step in the delivery of our mobile payments strategy. We are working with partners and organisations across the mobile ecosystem to make the future of payments a reality for consumers, for retailers and for financial institutions. By 2020, we predict that more than half of all our transactions will be carried out on a mobile device. Our investment in the Mobile Money Network will support our aim to deliver a wide range of secure and reliable mobile payment services that help our members tap into the potential of m-commerce.”

Monitise, one of MNN’s co-founders, announced a announced a £24.7 million investment from Visa Europe last year.
