The 'payto' URI scheme for payments
draft-dold-payto-14
Abstract
This document defines the 'payto' Uniform Resource Identifier (URI)
scheme for designating targets for payments.
A unified URI scheme for all payment target types allows applications
to offer user interactions with URIs that represent payment targets,
simplifying the introduction of new payment systems and applications.

1. Introduction
This document defines the 'payto' Uniform Resource Identifier (URI)
[RFC3986] scheme for designating transfer form data for payments.
1.1. Objective
A 'payto' URI always identifies the target of a payment. A 'payto'
URI consists of a payment target type, a target identifier and
optional parameters such as an amount or a payment reference.
The interpretation of the target identifier is defined by the payment
target type, and typically represents either a bank account or an
(unsettled) transaction.
A unified URI scheme for all payment target types allows applications
to offer user interactions with URIs that represent payment targets,
simplifying the introduction of new payment systems and applications.
