Verified Identity
Every driver fuels through the Piston app, tying the transaction to a verified person and device.
Fueling without cards, shared PINs, or card-on-file risk.
Drivers fuel through the Piston app. At most sites they unlock the pump directly; authorization-code and QR experiences support other enabled locations. Every flow is completely cardless.
