Do I Need to be Able to Charge Credit Cards?
You do not have to be able to charge credit cards. atheleteReg handles all credit card charges securely for participants registering online, and forwards registration fees to event directors. See Forms of Payment Accepted and How to Setup or Edit your Event's Payment Method for more information.
However, if you are interested in a day-of-registration solution check out LiveReg! A great way to make day-of-registration easy for you and your participants!
