At Humboldt University in Berlin today, Google's Eric Schmidt announced Google One Pass, a service that lets publishers set their own prices and terms for their digital content.

With Google One Pass, publishers can maintain direct relationships with their customers and give readers access to digital content across websites and mobile apps.

Readers who purchase from a One Pass publisher can access their content on tablets, smartphones and websites using a single sign-on with an email and password. The service helps publishers authenticate existing subscribers so that readers don?t have to re-subscribe in order to access their content on new devices.

With Google One Pass, publishers can customize how and when they charge for content while experimenting with different models to see what works best for them?offering subscriptions, metered access, "freemium" content or even single articles for sale from their websites or mobile apps. The service also lets publishers give existing print subscribers free (or discounted) access to digital content. We take care of the rest, including payments technology handled via Google Checkout.

German publishers Axel Springer AG, Focus Online (Tomorrow Focus) and Stern.de joined Eric at Humboldt University today as some of Google's first Google One Pass partners. Other publishers already signed up include Media General, NouvelObs, Bonnier?s Popular Science, Prisa and Rust Communications.

Google One Pass is currently available for publishers in Canada, France, Germany, Italy, Spain, the U.K. and the U.S.
