Bango says this will allow users to buy game credits, apps and other virtual goods through "frictionless operator billing, paying on their phone, without the need to register personal details."
Bango also has deals with Google (Play), Amazon, BlackBerry App World and Opera's Mobile Store. The company added that its conversion rates are higher than the industry average for carrier billing:
Conventional operator billing is expected to achieve a 40% conversion rate. Put simply, most mobile commerce customers who click ‘buy’, do not successfully buy. Billing with the Bango payment platform delivers an average conversion rate of 77%. Most users who click ‘buy’, do buy.
While carrier billing is useful in countries where there are many "unbanked" or where the specific transaction is likely to be conducted by a younger user, in the US and much of Europe credit cards are a preferred method of payment by most adults.
Carrier billing is much more widely available than other forms of mobile payments for obvious reasons. However carrier fees are much higher typically than credit card fees and settlement can take months depending on the country.
Even though Facebook eliminated Facebook Credits, which was a surprise to me, it's possible that Facebook will eventually acquire a mobile payments provider. Bango's market cap, for example, is only $118 million. Facebook could buy the company and associated revenue stream, as well as a set of global carrier relationships -- instantly.
