The objective of the client was to have an application built to implement a more efficient payment flow on Ingenico terminals iCT250 and iPP350 to accept card payments for both credit cards and private label cards (gift cards, countdown cards, loyalty cards, etc.). For private label cards, the payment is to be processed by the client's existing payment gateway service, CardDog. For credit card transactions, the payment is to be forwarded to First Data Payment Services by the CardDog portal for processing. In addition to performing transactions, the application also stores transaction details in the device for printing batch reports.
The application works in two modes: Standalone mode and POS mode. In standalone mode, the user has to select from a list of menu items a single transaction to be performed; whereas in POS mode, the application listens for a transaction request from a POS PC application that can come either via TCP/IP or USB based on the configuration settings in a parameter file.
