Google announced their new One Pass Micropayment system today. The new system allows publishers to offer different payment methods for content. The system will give readers the ability to access digital content on different platforms such as websites and mobile phones with one login.
Publishers can choose to use subscriptions, metered access, freemium and sinlge articles.
The system is supposed to streamline the process by keeping up with all the necessary components from login, authentication through the checkout process via Google Checkout.
This looks very interesting and I tried to signup. However the signup is currently not working and just cycles through to a websearch form.
Here is the video from Google explaining the system.
