The World Wide Web Consortium (W3C) has released a First Public Working Draft of its Payment Method Manifest. The document, which is intended to become a W3C Recommendation, addresses the following use cases:
The owner of a payment method wishes to authorize only certain parties to distribute payment apps that are capable of implementing the payment method
The owner of a payment method wishes to confirm the authenticity of a particular payment app
When the user has not yet installed a payment app for a payment method, the user agent can provide an improved user experience for procuring one
