Credit card value chains are quite complex. With all the new payment alternatives coming in (Square, Boku, Noca, Google and Visa's digital wallets, etc.), I thought of sharing an overview I had created some time back.
This is of course a basic view, and shows the value chain. I will post more information about all the fees and payment flows later. The interesting parts of the value chain are all the points of potential disruption. Paypal is the current Champion of Disruption, of course.
