Roaming for charging-station owners and operators: why not every charging card works

Roaming does not mean that every charging card or app will automatically work at a charging location. A route between Smart Fuel Pass and the issuer of a charging card must first be activated for the relevant service and country.

What roaming means

Roaming lets a driver use a card or app issued by another charging-service provider at a location connected to Smart Fuel Pass. The owner or operator of the charging station still controls the location, its connectors and its tariff. Smart Fuel Pass coordinates the technical and settlement route only where an active partner route exists.

What must be in place before a card can work

• Technical connection: the systems must exchange location, connector, availability, tariff and session data reliably.
• Commercial settlement: the card issuer and the charging service must agree how sessions, invoices, corrections and disputes are settled.
• Legal and tax handling: the route must work for the applicable country, contracts and charging documents.
• Payment assurance: the partner route must provide a reliable settlement and payment process. Smart Fuel Pass settles completed charging sessions for station owners or operators and therefore cannot accept an unverified payment route.

When to consider a card accepted

Consider a card accepted only after the partner route is live in production and the location is listed or confirmed as available for that route. Do not promise acceptance solely because the card brand is well known or because an integration is being discussed. Availability can also depend on the country, the exact location and the connector.

What we need from the owner or operator of the charging station

• Keep the location, address, GPS coordinates, access setting and connector data correct in the portal.
• Assign and test the tariff that should be shown to drivers before charging.
• Make the location public when it should be available to outside drivers; private or hidden access settings can intentionally limit who can find or use it.
• Test the normal charging journey before announcing availability to drivers.

Roaming is not the same as map visibility or card payment

A location appearing on a map does not by itself prove that every roaming card works there. Conversely, a technically active route may take time to appear in a partner's map or navigation service. QR payment and a physical payment terminal are separate payment journeys; they do not automatically enable third-party charging cards.

What to send to support if a card is declined

Send the card issuer or app name, date and time, location name, connector or EVSE identifier, session or transaction ID if available, and the exact message shown. This lets us check the right route. Do not send a full card number, CVV or PIN; provide only the last four digits if support specifically asks for them.

Important: Partner availability changes as integrations go live. Treat a card as supported only when its route has been activated and confirmed for the relevant location.
