You cannot migrate payment systems one at a time. Authorization, clearing and settlement involve issuers, acquirers, processors and card schemes, each working to its own timeline. Terminals and ATMs stay in the field for years, and every hardware change requires PCI and scheme certification. The overview covers what BIS Project Leap showed about cross-border migration and the PCI Security Standards Council’s migration timeline.
If your work involves authorization flows, key management or scheme certification, start with the overview. If it does not, Financial Services is the better starting point. In the intensive, you map your authorization path and terminal estate and leave with a sequenced migration plan. We teach both courses from the Payments Extension of the Applied Quantum PQC Migration Framework.
