The experience of waiting in lines is a common concern for people across different aspects of life. In educational settings, students are often delayed during meal payments, which needs effective solutions. This study aimed to address the concern by creating a Self-Service Kiosk using liquid crystal display modules. Methodology: A quantitative approach and an experimental research design were used to assess the processing speed, accuracy speed, and transaction speed of the device. Results: The results of the study proved that the self-service kiosk effectively displayed information on the LCD 20x4 screen for as early as 0.24 milliseconds. This indicated varied button response times, with "add to cart" consistently fast averaging 0.13 milliseconds, while "reset cart" was slightly slower at 0.15 milliseconds. The "Total Price" button maintained stable response times at 0.24 milliseconds. The processing speed showed an average of 100% accuracy rate for all buttons, while the transmission speed between the kiosk and the host device displayed as fast as 0.193 milliseconds, which emphasized the importance of button responsiveness. Discussion: The purpose of the Self-Service Kiosk was to enhance efficiency and augment customer experience in the context of a school canteen, which aided in creating a simplified ordering system and optimizing workflow. The success of each trial was evident, which affirmed the reliability and effectiveness of the kiosk. Recommendation: Future researchers are recommended to integrate higher-quality materials to improve the device's performance. Exploring alternative features could optimize the user experience in similar settings while considering possible limitations.
