Modules are php classes that can be 'dropped' into Zen Cart to provide extra functionality during Checkout.

Currently there are 3 types of modules.

Payment Modules

These are classes that allow you to add different methods of collecting and validating payment details. This could be something as basic as allowing a COD payment method where no details need to be checked, to connecting to an account to validate the Credit Card Details, adn check that sufficient funds are available.

Shipping Modules

These are classes that are used to calculate the cost of shipping items, they may act locally, or they may connect to service providers (like ups or usps) to calcuate shipping prices.

Order Total Modules
