The payment form re-confirms the shopping cart, but without the options to change the number of tickets or remove a ticket. The payment fields required can vary widely; if the shipping option is enabled, the purchaser’s address will be required. Authorize.net will request the usual credit card information, etc.
Credit card numbers are never saved to your site by any payment gateway developed by or sold by Joe Dolson Accessible Web Design; but I can’t make guarantees about any payment gateways you have custom developed or purchase elsewhere.
