Cardlock Fuel Solutions for Fleets — Secure, Traceable, Nationwide
DieselInBulk offers modern cardlock fuel services designed for fleet operators across South Africa. Our cardlock solution provides secure site access, transaction-level reporting, flexible controls and competitive pricing for commercial customers.
What is a cardlock?
A cardlock is a secure fuel dispensing system that allows authorised drivers to refuel at unmanned or semi-manned sites using a fleet card. Cardlocks eliminate the need for cash transactions, reduce fuel misuse, and provide detailed transaction records for each vehicle and driver.
Key benefits for fleet operators
- Security & control: Restrict fuel types, volume limits and time windows per card.
- Detailed reporting: Per-transaction data including vehicle ID, driver, time, volume and price for seamless accounting.
- Cost management: Consolidated billing and flexible credit terms for approved customers.
- Nationwide access: Use at participating DieselInBulk locations and partner networks for wider coverage.
- Integration: Exportable reports and APIs to integrate with fleet management and ERP systems.
How DieselInBulk cardlock works
We issue fleet cards to authorised drivers. Each card can be configured with controls such as maximum litres per transaction, allowed fuel types, and daily spend limits. When a driver refuels, the transaction is logged and transmitted to our back-office system for reconciliation and reporting.
We support both physical fleet cards and digital/mobile token solutions where available. Card setup, activation and replacement are managed centrally by your account manager for quick onboarding.
Reporting and fraud prevention
Our reporting tools allow fleet managers to monitor fuel usage in near real-time, set alerts for unusual activity, and export data for accounting. We use transaction validation rules and geo-fencing where possible to reduce the risk of fraudulent activity.
Pricing & account options
Cardlock pricing is typically structured with either per-litre billing at commercial wholesale rates or a consolidated monthly account with agreed credit terms. Volume-based discounts and contract options are available for larger fleets and long-term customers.
To receive a tailored cardlock proposal, contact our sales team with your fleet size, average monthly litres, and preferred billing terms.
