Pump Machina's institutional engineering knowledge — payments, machine integration, market knowledge, and Pump Machina's own architecture.

Machine Integration — OverviewHow an authorized payment reaches and controls the equipment. This domain begins where Operational Authorization ends: the software has decided to release a machine, and something must turn that decision into a signal the equipment understands.Payment Systems — OverviewThis section explains how payment works in a self-service laundry, independently of any single payment method, and then documents each method (PIX today; cards and others later), the providers, and the concrete Pump Machina implementation.
