Make no mistake though, these cards exist only to make the issuers money, and if you don't utilize them carefully then you could easily end up being worse off. The standard rates of rewards cards are generally higher than those of ordinary cards, to cover the costs of running the reward scheme, and so if you're not getting the most out of the bonuses on offer then you're probably better off with a cheaper card without the rewards feature.

As with all credit cards, the most important thing you can do is to pay off your balance in full each and every month. Any rewards points you build up will be totally dwarfed by interest charges if you allow a balance to build up - this is, after all, how the card issuers plan to make money from you. By paying your bill on time each month, you'll avoid interest charges and other fees, allowing the value of the rewards points to shine.

Secondly, make sure that you're aware of any special deals between your card issuer and retailers or service providers - in many cases you can earn double or triple points by choosing one retailer over another, and if price differences aren't an issue then choosing your shopping outlet wisely can help your points build up much more quickly.

In these days of online account operation for all sorts of services, it's easier than ever to pay energy bills and the like with your credit card. These kinds of bills are often a major part of a household budget, so why not use them to earn rewards? Make sure though that you don't have to pay a credit card surcharge, or the benefits could well be outweighed by the extra cost over paying by cash or cheque.

It also makes sense to shift as much of your everyday spending as possible onto your card, so that your points tally will grow at an even greater rate. Groceries, vehicle fuel, subscriptions, car parking costs - any time that you can choose plastic over cash, you should do it. Just ensure that you don't allow your card balance to slip into the red from month to month, as paying interest on essential everyday expenses is not a wise move for your budget.

Another way to ramp up your points total is to make use of bonus points if available. Many card issuers offer special promotions at certain times of the year, during which you'll earn more points than usual. If your card issuer does this, then try and save any major purchases until one of these bonus periods.

Finally, one easy way to increase your points earning potential is to take advantage of the additional card facility. If your spouse, partner, or other close person that you can trust also uses a card linked to your account, then you'll accrue points via their spending too - just be sure they pay their part of the bill when the statement arrives!

So as we can see, there's more to rewards cards than just spending as normal. By taking advantage of the tips we've covered, you can ensure that your benefits from using a reward card will be maximized while the card issuer's profits at your expense will be eliminated!
