Request to Pay can be used in a variety of ways. Financial service providers are involved in this as intermediaries and, in individual cases, even as pathfinders. They can contribute to deployment concepts, place innovative value-added services on the market and ultimately achieve a closer customer-bank relationship. The whitepaper examines application scenarios for Request to Pay as an invoice supplement, as a missing piece of the puzzle on the way to media-discontinuity-free, fully digitalised payment processes, as a cornerstone for completely new payment models or as a convenient solution for payments at the point of sale. Since all financial service providers are effectively starting from scratch when it comes to electronic payment requests, early entrants can realise great market opportunities here.
