PAX builds the Android terminal. Paying.co builds the workflow running on top of it — custom forms, multi-step transactions, native Android applications, MDB and Pulse connectors, and EMV Level 3 certification when the project requires it.

Countertop, unattended and handheld devices all share the same PAX Android foundation. We build the application and integration layer around the deployment rather than forcing one generic terminal flow everywhere.
Retail, hospitality and QSR workflows with custom checkout, tipping, split tender, loyalty and onboarding.
Vending, parking, EV, laundry and self-service terminals bridged into the machine through MDB or Pulse.
Pay-at-table, field service, ridesharing and queue-busting with multi-step workflows and remote TMS deployment.
The device is only the starting point. Paying.co builds everything that turns PAX hardware into a deployable business application.
Applications built directly against the PAX Android SDK and payment events, using the full UI and system capabilities of the platform.
Multi-step transactions, loyalty enrollment, onboarding, cross-sell, data capture and guided self-service journeys.
Custom protocol bridges between modern PAX Android devices and vending, laundry, parking, EV and unattended equipment.
When certification is in scope, we run the separate EMV workstream end to end across processor and card-brand test plans.
The architecture stays straightforward: native PAX Android at the edge, processor or middleware connectivity underneath, and your business workflow on top. No generic wrapper pretending the device is just another tablet.
We have shipped PAX integrations across common gateway, middleware and direct processor paths. The integration layer is usually well-trodden ground, not a research project.
