Spook a customer once with an insecure credit check and he never comes back. To protect against credit-card theft, transactions are isolated from the Net. At IEG, for example, credit card numbers arrive encrypted. They are then passed through a firewall and into separate Oracle servers. The data then go directly over dedicated fiber-optic lines to banks.
Banks check and clear the payment without sending the information back over the Internet.
In another interesting technical twist, IEG offers interactive games. One, based on that old stand-by Space Invaders, substitutes female body parts for aliens. Players shoot down or capture the parts. Winners are rewarded with a full nude image. Keeping you coming back and showing you the coolest, neatest things.
