<br/><br/> This paper aimed at developing the design, the creation, the testing, and the evaluation of<br/>an IoT-based touchless vending machine system to enhance cleanliness, convenience, and<br/>user experience in public spaces, specifically for restroom needs. Physical contact with<br/>the machine is the most common in traditional vending machines, and this only helps to<br/>raise the risk of spreading bacteria and viruses. Touchless technology is popular in<br/>several fields, but there is no evidence yet on its use in vending machines for public<br/>hygiene items. This work will fill that gap through the use of QR code scanning and the<br/>PayMongo API, enabling secure and instant transactions. The purpose of this work is to<br/>advance the research for developing an IoT-based touchless vending machine system that<br/>creates QR codes for product selection and payment, ensuring a seamless and enjoyable<br/>experience. The system is embedded in an Arduino-compatible microcontroller and a<br/>web platform that is connected to the PayMongo payment system. The research included<br/>functionality, accuracy, and security testing processes in which the performance metrics<br/>of the system were determined with factors like QR code scanning, product selection,<br/>proceeding to the payment page, payment verification, product dispensing, item<br/>dispensing accuracy, website compatibility, and error handling. Every single test was<br/>passed, thus proving the whole system is working correctly. The ISO 25010:2023 criteria<br/>were used in the evaluation, with a focus on functional suitability, performance<br/>efficiency, compatibility, usability, and user satisfaction. The grand weighted mean of<br/>4.49, with a descriptive rating of “Very Good”, indicates high user satisfaction and<br/>effectiveness in providing a touchless, sanitary vending experience. This study helps to<br/>advance touchless vending technology by providing an efficient, secure, and user-friendly<br/>option for public areas.<br/>Keywords: Touchless vending, IoT technology, QR code payment, PayMongo<br/>API, Hygiene
