For STi, a large international calling card company, I was tasked with building dynamic card selection tools to help users select the calling card that best suits their needs. Using the widely popular FlexCart as a starting point, I built a custom card selector that allows users to filter available cards on a number of criteria while displaying rates based on their call origin and destination.

The card selector makes calls to ASP.NET webservices to retrieve card information, get filter content and update business logic. Flex also performs order validation before passing order info to an ASP.NET shopping cart for completion.
