W3C Web Payments Community Group
A Web Payments CG which was set up in 2011 by Manu Sporny. Its stated aim:
The purpose of the Web Payments Community Group is to discuss, research,
prototype, and create working systems that enable Universal Payment for the Web. The goal is to create a safe, decentralized system and a set of open, patent and royalty-free specifications that allow people on the Web to send each other money as easily as they exchange instant messages and e-mail today. The group will focus on transforming the way we reward each other on the Web as well as how we organize financial resources to enhance our personal lives and pursue endeavors that improve upon the
human condition.
The group is active, further information is available on the wiki and email archive.
