Bango, the mobile payments and analytics company, has signed an agreement with Opera Software to provide mobile payments for the Opera Mobile App Store.

The store currently delivers 1m app downloads a day through a browser-based interface which works with any mobile browser, including the Opera and Opera Mini mobile browsers. Bango will provide charge-to-mobile bill and other payment methods, such as credit card billing. The Bango mobile payment feature is expected to go live and generate revenues in Q3 of 2011, the second quarter of Bango’s financial year.

“Bango is delighted to now provide carrier billing for the Opera Mobile App Store; our second major app store,” says Bango CEO, Ray Anderson. Bango is continuing to develop a number of other significant app store opportunities, and our progress gives us confidence that we are well placed to accelerate growth in future periods.”

Earlier this month, Bango revealed that it was providing billing services for RIMs BlackBerry App World app store.
