Compare payment systems
Registered systems side by side, across the capability groups, their architecture and their observed coverage. Differences are described, never scored.
Capability comparison
The same capability groups across every registered system. Differences are described; nothing is scored and nothing is called better.

Architecture comparison
How each system is built, from its published architecture profile. A system with no published profile has no row content — that is an absence of research, not an absence of architecture.
