Cardlock

A fueling site or system that authorizes commercial fuel purchases using cards, PINs or account credentials.

Why It Matters

Cardlock affects route planning, accepted locations and whether a listed discount is likely to apply on regular lanes.

How It Shows Up

Example

A card can work at many stations while cardlock applies only at selected stops. A carrier should check its recurring lanes before treating coverage as useful.

Common Mix-Up

Acceptance does not guarantee the best price. A card may authorize a purchase where the advertised discount does not apply.
