Laravel Web Application

Prepaid Credit Card & PreProcessor Application


An application based on Laravel framework 5.5 was built for our client where they can manage all the prepaid cards sold by them. Our client sells prepaid cards to the corporate's directly or through some distribution partners(Master clients) through authorized banks. The distributors who sold the cards can send requests regards to the cards to the client for adding funds to the cards they purchased and updating the status of the cards.


Client’s main requirement was to have two different applications or instances (admin portal and corporate portal) where one of the application is completely looked by the client and the other is for the distributors (Master clients)where they can have an overview of their respective cards, users and his requests


The application which is for admin should contain all the information regards to his employees, total cards, distributors(Master clients), all the requests coming from the other instance for status changes or recharge of the cards.


Client also requires an overview of all the user log and activity log of his users who is logging into the application and performing actions based on their roles.

Business Requirements 



Integrating Amazon API for all the requests that are coming from corporate portal to admin portal.  Integrating of Amazon S3 into the application where we will be saving all the documents that are uploaded by the corporate portal.


Integrating bank API for verifying the requests that came from corporate portal and get the valid response. Integrating JS widget where we need to get the response from the webservice and making the widget secure.

JS widget
