Shopping scenario : In each of the following scenarios, you
will be shopping your next cellular phone from ARIX. You start by
looking at the catalog. When you have selected your favorite model,
you submit the order whereby the payment negotiation starts. When
you and your merchant have agreed on a payment method, the order is
processed, and you get an electronic confirmation of your
order. Your new phone will be delivered to you the next day.
- Pre-JEPI scene 1
- No payment negotiation. The merchant only supports
a single payment mechanism which you don't have. Too bad!
- Pre-JEPI scene 2
- No payment negotiation. Knowing that different customers use
different payment systems, the merchant has decided to support as
many payment systems as possible. That could be quite a long list !
- Post-JEPI scene 1
- An example with a minimum of UPP negotiation. The negotiation
starts after the client submits an order. The merchant sends then
the invoice along with payment options he supports. The demo
contains detailed information about messages exchanged by the
client and the server. This is the scene (to be) implemented by
the JEPI prototype in Oct/Nov 96.
- Post-JEPI scene 2
- The negotiation starts earlier in this scene. The merchant
sends payment options to the client along with the product catalog
to avoid future client inquiries about payment systems.
- Post-JEPI scene 3
- With payment negotiation. When requesting the
product catalog, the client also asks for payment options that
the merchant supports. At the same time, the client announces one
of his favorite payment systems to the merchant.
- Post-JEPI scene 4
- With payment negotiation. This scene is similar to Post-JEPI
scene 1 and 2, but this time, the client does not support any of
the payment systems suggested by the merchant. So, he comes up with
NOTE: In all post-JEPI scenes, neither client nor merchant
sends an exhaustive list of all payment systems he supports (compare
pre-JEPI scene 2). He sends only a subset of payment systems that
he believes that the other party might be interested in.
