Rewards generally fall into one of three categories: cash, points, or miles. The cash rewards can help reduce your credit card balance. Travel rewards can help you earn free trips for yourself and your loved ones. You can use rewards to purchase holiday and birthday gifts. You also can invest the rewards you earn. For example, the Fidelity Investment Rewards Signature Visa puts your rewards into an investment account.1 The Wells Fargo Cash Wise card uses your rewards to reduce your Wells Fargo mortgage.
