Payment Infrastructure for Unattended & EV.
AFIR-compliant payment acceptance for charge points, vending, and parking. Hardware-agnostic, multi-acquirer, and white-label — so you can comply without locking into a single vendor’s ecosystem.
AFIR mandates card acceptance at charge points.
The Alternative Fuels Infrastructure Regulation (AFIR) requires card payment acceptance at EV charging points. For Charge Point Operators, that means deploying payment infrastructure that’s fast to roll out, works across terminal hardware, and doesn’t tie you to a single acquirer.
Most payment stacks were never designed for unattended, multi-vendor, multi-acquirer environments. Field39 was — the switching layer is hardware-agnostic and acquirer-agnostic, so compliance doesn’t come at the cost of control.
Built for terminals no one is standing next to.
Switching that adapts to your hardware, your acquirers, and your brand — with the operational visibility unattended fleets demand.
Hardware-Agnostic
Works with PAX, Castles, IDTech, Miura, and others. Connect any terminal or kiosk — you’re not locked to one vendor’s devices.
Multi-Acquirer Routing
Choose acquirers by cost, availability, or card type, with automatic failover when one goes down.
Fleet Monitoring & Diagnostics
Dashboard39 gives real-time fleet monitoring and remote diagnostics across every unattended terminal.
Simple HTTP/JSON API
Integrate with any terminal application or kiosk software — no ISO 8583 knowledge required on the device side.
White-Label
Your brand on the payment experience, end to end. Field39 stays invisible.
One switching layer for every unattended use case.
The same infrastructure that powers AFIR-compliant charge points runs vending, parking, fleet fueling, laundry — any unattended environment where cards need to be accepted.
And where you have manned terminals at adjacent sites, CardPay39 gives you a certified payment app on the same platform — one stack across attended and unattended.
