Prepaid Union needed a complex combination of front- and backend applications where security was the number one requirement. The various front-ends that needed to be developed focussed on the different client groups (consumer and business). The consumer front-end is openly accessible via www.prepaidunion.com while the business interface is only accessible through secure double login.
The front-end was developed using css and Javascipt (mainly jQuery). Communication between application and frontend, shop application, API and callback is Json-RPC where MySql is being used as the database.
The backend of Prepaid Union was build in PHP in ZEND framework and consists of many functionalities that aim to help and inform the clients during and after their ordering process, all in an automated way. External parties that wish to use the basis of the services of Prepaid Union can connect through a set of API’s.
