Retailer Barnes & Noble Inc. is making it easier for NOOK users to buy digital goods through their e-readers. Its digital media and content subsidiary, NOOK Media LLC, has signed a deal with online payment processor Fortumo to provide in-app purchasing for games and apps offered on NOOK devices.

Through Fortumo services, app and game developers will be able to add payments to their digital wares, selling premium digital content seamlessly to NOOK customers in the NOOK Store. Fortumo also brings its one-click checkout process that lets customers pay for purchases with a single click after their first purchase. Fortumo's platform stores payment credentials so customers don't have to enter credit card information.

"We are thrilled to bring in-app purchasing to NOOK with Fortumo for our community of developers so they can foster a profitable relationship with their customers, while also providing our NOOK customers with a more in-depth app experience and an even wider selection of popular apps," said Claudia Romanini, VP of NOOK apps at NOOK Media. "We look forward to adding thousands more apps that feature in-app purchasing over the coming weeks and months to expand NOOK's already wide array of digital content offerings."

Along with processing for in-app payments, Fortumo will also provide developers with the tools and resources they need to implement in-app purchasing, Barnes & Noble said. The tools will include a dashboard with real-time analytics.

"In-app purchasing makes it possible for developers to ensure the customer only pays when they absolutely love the app. This has proven to be a compelling value proposition for customers and a very successful strategy for developers," said Rain Rannu, co-founder and CEO of Fortumo.
