Bidder paddles are a must have for any charity event. Your goal is, of course, to raise as much money as possible. The paddle raise is a great way to harness audience excitement at the event because donors can see who is giving and the bandwagon effect as well as their competitive nature encourages them to donate, usually at a higher amount. Plus, you will build long-term support by recognizing the people who are supporting you. You can't do this with mobile giving.
