If you are keen to reap rewards when you spend but are restricted by a bad or non-existent credit rating, the good news is that there are still cashback cards available to you. These are not nearly as rewarding as others on the market though, so your priority should be to rebuild your credit rating to make yourself eligible for these more competitive cards in the future. To rebuild your score you will need to use your credit card regularly, never missing a payment and always stay within the limit. Use your cashback card to get a small reward for repaying in full every month while you work towards rebuilding your credit rating. Only get these cards if you can pay the balance off in full every month as the interest rate is likely to be higher than standard cards.
