All the customer has to do is click an icon that looks like a printer. Once their printer has printed out the form, the customer fills in the form with a pen, writes a check or inscribes credit card information on the form, and mails everything in. Typing in their credit card or digital cash numbers. This is the least secure way to make a purchase online. Profits aren't, but profit margins are.
