This research proposes the development of a mobile phone and camera rental application named QuickRent, using the prototyping method to enhance the efficiency of the leasing process. The prototyping method was chosen for its ability to allow developers to evaluate and improve features based on user feedback from the outset of the design process. The application aims to address challenges in the traditional rental process, such as improving transaction efficiency and user trust. The research involves a comprehensive system analysis, design, and implementation, with blackbox testing confirming the validity and usability of the features. The Quick-Rent app ensures transaction security, product quality, and user accessibility, making it a viable solution for individuals who cannot afford the latest gadgets or need them temporarily. The prototyping method enables iterative customization and enhancement of features, leading to heightened user satisfaction and trust in the system. The study concludes that the prototyping technique effectively addresses the challenges in the rental process and enhances the user experience.This research proposes the development of a mobile phone and camera rental application named QuickRent, using the prototyping method to enhance the efficiency of the leasing process.
