Everybody is getting into the mobile payment business these days. While Google Wallet has been one of the most talked about (and hacked) mobile payment options, Opera now offers their own alternative.

Opera Software, developer of the Opera browser, announced today the launch of the Opera Payment Exchange program. Their goal is to provide the world’s best experience in mobile payments. OPX allows users of Opera Mini to carry out mobile transactions “securely and simply with payment instruments they know and trust.”

OPX offers an API that Web sites can use to offer an easy way for Opera Mini users to make mobile payments on their sites. They claim that every Web site that integrates OPX into their mobile site stands to gain these benefits:

For Opera Mini users, OPX will provide a secure and trustworthy mobile-payment experience that is ubiquitous, convenient and easy to control.

For publishers, OPX helps maximize the potential of their existing billing connections with carriers, payment instrument providers and payment gateways, by increasing conversions through merchandising intelligence based on transactions performed on the publishers website, and through a trusted user experience.

For operators, OPX provides a new revenue stream with standardized integration, better support and retailing insights based on carrier billing.

For payment providers and payment gateways, OPX will overcome inconsistent user experience and fear of fraud with one-click, native support for payment instruments.

“At Opera, it is all about giving the user the best possible experience,” said Mahi de Silva, EVP for Consumer Mobile, Opera Software. “Mobile payments have so far been a privilege for users of high-end devices in developed markets. With OPX, Opera is expanding this to all devices, no matter the location, carrier or payment instrument by giving the stakeholders in the ecosystem the right technology to carry out the transactions.”

It’s an ambitious plan that already has secured a few partners including InMobi SmartPay, Yandex.Money and Bango who will use OPX for their mobile payments in parts of the world that aren’t serviced by the big players yet. They expect OPX to be rolled out to more parts of the globe throughout the year.

Opera will be showcasing OPX at their booth at the Mobile World Congress this week.
