- Engineers learning the machine-to-machine stack
- Worth noticing
- The reference treats autonomous machine payments as a first-class layer alongside identity, connectivity, messaging, and management.
Field notes
The reference uses a dependency model: settlement depends on management, management depends on connectivity, and trust begins with a device-held key. Its examples span both long-established infrastructure and newer payment mechanisms, including GSMA SGP.32 for screenless eSIM deployments and ISO 15118 Plug & Charge. The navigation also separates protocols, standards, payments, and glossary material from the main stack.
