       Title     : SELECTING PAYMENT MECHANISMS OVER HTTP 
                   Or, Seven Examples of UPP Over PEP (as used in JEPI)

The Joint Electronics Payment Initiative aims to bring key industry players
together to assure that multiple payment protocols can operate effectively 
in Web applications. The concrete goal is automatable payment selection 
over HTTP.                                                       

The first step towards this was Don Eastlake's development of the
Universal Payment Preamble, which is also available as an internet-draft 
(draft-eastlake-universal-payment). The second is the development of an 
HTTP Extension Protocol to embed UPP in HTTP. The latter proposal is part 
of the chartered activities of the IETF HTTP G (draft-ietf-http-pep-03).   

This document describes how to use UPP over PEP to support payment 
selection between clients and merchants. It explains basic operations:  
requesting available payment choices, presenting multiple choices, 
demanding a selection, making a selection, and accepting and rejecting 
choices.

Internet-Drafts are also available by mail.
                                                     
Send a message to:  [e-mail]. In the body type: 
     "FILE /internet-drafts/draft-khare-jepi-uppflow-00.txt".
                                   
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
