For people who manage their credit cards responsibly, using a rewards card is a good thing. But a more far-reaching way to use those rewards would be to donate them to a charitable cause – opportunities that include university alumni associations, sport teams, education, hunger, etc. Your rewards may not make a big dent in the need, but collectively it can begin to make a difference.

The charitable concept has been around for more than two decades. One of the more successful programs is that offered by the Target Corp. Since 1997, the ‘Take Charge of Education’ program has been offered to consumers who want to make a difference when using a credit card. As of September 2010, total contributions of $298 million have been earned by REDcard® holders that benefit public education.

For cash strapped consumers who want to contribute to worthy institutions, the cards will give them that opportunity without adding the burden of additional debt to their credit cards. Consumers also have the option to redeem their traditional cash back rewards and forward them on to the charity of their choice. The goal is not to get users into credit card debt, but rather to get people who are already making purchases with a credit card or debit card to make a positive out of what could be a negative.

The Discover cash back bonus charitable partners include the American Cancer Society, ASPCA, American Red Cross, Children’s Miracle Network, Make-a-Wish, Operation Homefront, World Wildlife Fund and Junior Achievement. American Express’ Members Project card members can donate their reward points to charities. Look at the online information about your card's program to explore the options.

The one potential downside to giving your rewards to charity is that the contribution won’t be tax deductable. If the tax break is necessary, you may be better off personally using the rewards and making a donation in another way. And remember, no matter if a card company offers a giving program for charity or you choose to give you rewards on your own, good things that can come from carrying a piece of plastic.
