Abstract

An operating machine known as "Intelligent Pre-paid Dispenser" is developed. It is virtually a vending machine that is designed to sell and cater the need of multiple prepaid products in the Malaysian market. Instead of a card, the product sold is simply the commercial distribution of PIN and Serial Number of the product. In other words, the machine uses embedded technology where the stock of PIN based products is kept in soft form. There are three modes of operation which are Sales Activity Mode, Diagnostic Mode and Remote Management Mode. The sales and purchase activities is done in Sales Activity Mode which involve connection of main controller to several peripherals such as a mini printer for receipt printing, display for user interface, and money validator for authentication purpose. The management and configuration of the sales product database is done via Hyper Terminal in Diagnostic Mode. This includes several menus such as product list, available stock, sold counter and system configuration. For Remote Management Mode, the machine is developed to include a facility where some of the Diagnostic Mode functions can be done over SMS messaging from a remote cellular GSM terminal.
