The problem that currently exists with the purchase of fuel at gas stations is that it is still carried out manually where customers make payments in cash, which results in several problems such as mistakes in the process of returning money which takes a longer time, thus increasing the number of queues that occur at gas stations. This research aims to simplify the payment transaction process,
minimize calculation errors and shorten transaction times so as to minimize the number of queues at gas stations. Smart Card functions as a medium used to process transactions, where customers can make payments by tapping the Smart
Card on the available RFID Reader and selecting the type of Fuel (BBM) IaIu entering the amount of price you want to pay. With this tool, it is easier for customers to make payment transactions, can minimize queues at gas stations
when purchasing fuel oil (BBM).
