Arco indeed offers only a prepaid gas card to consumers and fleet credit cards to businesses. Therefore a good option for you can be a regular gas rewards credit card from a major bank. Such cards are not tied to a particular brand but can be used everywhere and allow earning points or cash back on all purchases. You can earn fixed rewards per dollar spent or you can choose the card that offers different rewards for purchases in different categories.
