Net Gain: Playing It Safe

Use a reputable, third-party payment-processing solution.
In order to accept credit cards, you’ll contract with a third-party payment processing company either directly or through your bank. Some companies offer online donation processing, terminal services (swiping credit cards as in retail stores) and/or authorization via telephone — and some do it all. It’s important to find a reputable third-party service that can manage all of the various ways you envision processing credit cards.
