PAX builds the Android-based terminal lineup powering kiosks, retail counters, unattended payment, and self-service worldwide. Paying.co builds the software that turns those terminals into complete workflow applications — custom forms, multi-step transactions, native PAX Android development, and MDB or Pulse connectors. When EMV Level 3 certification is required, that's a separate workstream we run end to end in the same engagement.
PAX's lineup spans countertop and retail terminals, unattended and outdoor payment kiosks, and mobile and handheld Android POS — all running on the same Android-based PAX platform with rich UI/UX capabilities. Paying.co builds custom applications, workflows, and EMV-certified integrations across the entire range. One engagement, one engineering team, one certification deliverable per processor.
Retail counters, hospitality, and quick-service running PAX's countertop Android terminals — A35, A50, A60, and A77. Paying.co builds custom checkout flows, tipping and split-tender logic, loyalty enrollment, onboarding forms, and the EMV Level 3 certifications that get your application into production.
Talk to our teamOutdoor-rated payment terminals for vending, kiosks, parking, EV charging, laundromats, and self-service. Paying.co builds the native Android application layer and MDB or Pulse connectors that bridge PAX to the machine. When the deployment also requires EMV Level 3 certification, we run that as a separate, well-scoped workstream alongside.
Unattended SystemsMobile and handheld Android POS for pay-at-table, field service, ridesharing, and queue-busting. PAX's A920 Pro, A920 Max, and A800 lineup — with Paying.co's custom apps, multi-step workflows, loyalty capture, and TMS deployment built on top.
Mobile DevelopmentPAX builds the Android terminal. Paying.co builds everything that turns it into a deployable workflow application — from the native Android application layer down to the processor integration. One vendor, one engineering team, one engagement scope.
Custom applications built native to the PAX Android platform — leveraging modern UI/UX, multi-touch gestures, and the rich application capabilities that come with Android, while integrating directly with PAX's payment SDK and event handlers.
Multi-step transactions, data capture screens, loyalty enrollment, onboarding flows, cross-sell prompts, and guided self-service journeys — designed and built native to PAX terminals, with the kind of UX users actually expect from modern hardware.
Custom connectors that bridge PAX terminals with legacy MDB and Pulse machine protocols. Modern cashless acceptance on vending, laundromat, EV, parking, and unattended equipment — no hardware replacement required.
When EMV cert is part of the project, we run it end to end — in-house, against your processor's test environment, with 130+ L3 certifications already shipped across Visa, Mastercard, American Express, and Discover scripts on PAX hardware.
PAX gave the payment terminal a true Android platform — rich UI, modern application capabilities, fast deployment, and a hardware lineup that covers everything from countertop to outdoor unattended. Operators choose PAX because the hardware is flexible, the ecosystem is open, and the platform is built for custom workflows. The application running on top of it should match that potential.
That's where Paying.co fits. We've completed numerous EMV Level 3 certifications across PAX devices, built custom forms and workflows running natively on PAX Android, and shipped MDB and Pulse connectors that bridge PAX terminals with legacy vending, laundromat, EV charging, and parking equipment. Deep integration experience with Datacap middleware, direct processor connections, and the broader payment gateway ecosystem.
The point is simple: you pick PAX because the Android-based terminal is the right tool for the job. We solve the software problem on top of it — with one team, one statement of work, and one certified deliverable per processor.
Talk to our PAX teamWe build where PAX actually wants applications built — native to the Android platform, integrated directly with the PAX payment SDK, and certified end-to-end through the processor's test environment. No wrappers, no middleware in the middle charging rent. The application is yours, the certification is yours, the source is documented.
Direct integration with the PAX payment SDK, BroadPOS, and the Android application framework. Modern UI, multi-touch, system permissions, and rich Android capabilities — layered on top of a certified payment foundation.
Seamless integration with Datacap middleware (NETePay, dsiEMVUS), direct processor connections, and gateways like Worldnet, BridgePay, Cardknox, and CardConnect. The connector layer is well-trodden ground for us — not a research project.
Custom connectors that bridge PAX terminals with MDB (Multi-Drop Bus) and Pulse machine protocols. Modern cashless acceptance on traditional vending, laundromat, parking, EV charging, and unattended equipment — no hardware replacement required.
PAXSTORE and Terminal Management System integration for remote deployment, configuration, and updates across your entire PAX fleet. New features and security patches pushed remotely — no physical access required to each terminal.
Paying.co has shipped EMV-certified PAX integrations across the gateways and middleware that matter for retail, unattended, and mobile environments — Datacap, Worldnet, BridgePay, Cardknox, and CardConnect, plus direct integrations into the major processors. If your business already routes through one, we drop into that flow. Need a direct processor cert? That's our specialty.
Deep, production-shipped integration with Datacap's NETePay and dsiEMVUS middleware on PAX terminals. The most widely deployed payment gateway in North American retail and unattended — and one we know cold.
Direct integration with Worldnet's payment gateway and unattended processing rails. Certified flows on PAX hardware, configured for the international and multi-currency deployments Worldnet specializes in.
Native integration paths into BridgePay's gateway and tokenization platform. Built and certified on PAX terminals for ISV and ISO partners who route their volume through BridgePay.
Direct integration with the Cardknox gateway and developer platform. Production-shipped on PAX hardware with full EMV L3 certification and tokenization support for retail and unattended.
Built to CardConnect's CardPointe and CoPilot platforms. We've certified PAX terminals into CardConnect's processing rails for ISV partners and direct merchant deployments alike.
Need a direct EMV Level 3 certification straight to TSYS, Worldpay, Fiserv, Global, Elavon, or another acquirer? That's our day job. 130+ L3 certs shipped across the Western Hemisphere.

Every Paying.co PAX engagement runs against a documented Statement of Work, with named owners on both sides, a defined certification milestone, and a deployment plan. Custom forms and workflows land in 4–8 weeks. MDB and Pulse connector projects land in 8–16 weeks. EMV Level 3 certification — a separate workstream with its own scope — typically runs 6–12 months depending on processor and card brand scope. You always know where the project stands.
We understand your business needs, target use cases, and existing infrastructure. Our team evaluates the right PAX hardware family — countertop, unattended, mobile — and maps the workflow architecture for your specific deployment scenario.
Custom forms, multi-step workflows, and user interfaces optimized for PAX Android terminals. Interactive prototypes validate the user journey on actual hardware before we commit to full development.
Our engineers build PAX-native Android applications with seamless Datacap, processor, and middleware integration. Payment logic, backend connectivity, MDB/Pulse connectors, and compliance handled across the build cycle.
When certification is in scope, we run the complete EMV Level 3 process across PAX devices — Visa, Mastercard, American Express, Discover — ensuring end-to-end compliance with all card brands and the processor's test environment before go-live.
Applications deploy across your PAX fleet via PAXSTORE and TMS integration. Ongoing monitoring, updates, and technical support — smooth operation across unattended, kiosk, and retail environments.
Same engineers, same project manager, same EMV cert team for the life of the application. When your processor releases a script update or PAX publishes a firmware change, you have a phone number that already knows your stack.
Tell us what you're building on PAX. We'll tell you what it takes to get it certified, integrated, and shipped — and you'll hear back from a payments engineer, not a sales rep.
