Google is developing a micropayment platform that will be “available to both Google and non-Google properties within the next year,” according to a document the company submitted to the Newspaper Association of America. The system, an extension of Google Checkout, would be a new and unexpected option for the news industry as it considers how to charge for content online.
Becoming more relevant for news and media companies?
Google describes its new e-commerce plans as “in production” and “currently in the early planning stages.” The company says that Google Checkout is currently equipped to handle subscription payments for news sites but describes the process for merchants as “fairly rudimentary” and says the system “could be improved to be more relevant for news and media companies.”
