As mentioned, the point at which the dialog for tip is presented (before or after CVM check) is a configuration option for the merchant. Keep in mind we are deploying a US solution first. We are also anticipating that in the US we will have signature as the primary CVM before PIN. From that perspective, our flow will should be a little less odd. That said, in the true Chip & PIN solution, once you ask for tip after PIN entry you as the merchant are opening yourself up to higher rates (Card Not Present) as well assuming liability for chargebacks. I don't know why a merchant would want to do that but as a platform we have chosen that use-case as an option.
