## Frequently asked questions

### What is a corporate fuel card?

A closed-loop payment instrument issued to legal entities, accepted only in the provider accredited network, with configurable per-plate limits.

### How does per-plate control work?

The system validates the vehicle plate at refueling time. If it does not match the card, the transaction is automátically declined.

### Is fuel card spending tax-deductible?

Yes, for Lucro Real companies, provided each refueling has an NF-e and the expense is linked to core business activity.

### What is the difference between a fuel card and a fuel voucher?

A fuel voucher is an employee benefit regulated by CLT; a fuel card is a corporate expense instrument with per-transaction NF-e and per-vehicle reports.

### Can fuel cards be used at any gas station?

No. Fuel cards operate within a closed accredited network. Map your fleet routes and verify the network covers at least 80% of them before contracting.
