The operating activities of a supermarket include all transactions. One of which is the payment of groceries. With a limited number of cashiers, it causes problems such as the buildup of queues at the cashier. In the consumer view, consumers often do not pay attention to the total price of the purchases taken. Thus, the budget does not match the accumulation of the items taken. This application was designed using the prototype development method and the brute force algorithm. The brute force algorithm looked for matches between the pattern and the text one by one from left to right. This algorithm was able to shift continuously every time a mismatch was found until the pattern was at the end of the text. The result of this study found that a mobile application made consumers finding out the accumulated prices of goods directly and easily by using a barcode scan on the goods. Moreover, it also eased to search for the desired goods by using the search feature based on product descriptions and product categories. Thus, consumers were able to control the spending budget according to the budget without worry at the checkout.
