The microcontroller based E-load vending machine provides an automated and more efficient method of reloading the cellular network subscribers. Unlike a human retailer, the machine automates the tedious task of the loading process, thus eliminating human error. The machine's microcontroller allows it to be independent and seldom requires human assistance. Also, using a 3rd party load retailer, the machine is capable of reloading across all 3 major cellular networks. With the use of this system, retailers will be able to practice their business without having to be on location at all times and also creates an investment opportunity for business people. This paper will discuss the implementation process, the technologies involved, the development of the system, and the results of the various test conducted to gauge its reliability. Recommendations were also cited to further improve the system and maximize capabilities.
