Automated IoT Payment System for Accommodation Services

Petković, Luka (author), Pilipović, Ratko (mentor)

The thesis describes the design and implementation of an automated IoTbased payment system tailored for accommodation services. The system leverages modern embedded technologies, specifically the ESP32 microcontroller, combined with a custom backend to enable secure, reliable, and efficient cash handling without the need for the host’s physical presence. The payment system is integrated within a modified safe, equipped with a touch display and a banknote validator, ensuring secure transactions. It communicates with a server via a REST API, providing real-time updates and management capabilities through a web-based frontend. The solution is adaptable and scalable, capable of meeting the evolving needs of the hospitality industry.

Abstract

Diplomsko delo opisuje oblikovanje in implementacijo plačilnega sistema na osnovi tehnologij IoT za potrebe nastanitvenih storitev. Sistem izkorišča sodobne vgrajene tehnologije, natančneje mikrokrmilnik ESP32, ki je povezan z namenskim strežnikom za zagotavljanje varnega, zanesljivega in učinkovitega upravljanja gotovinskih transakcij brez fizične prisotnosti gostitelja. Plačilni sistem je integriran v predelan sef, opremljen z zaslonom na dotik in validatorjem bankovcev, kar zagotavlja varne transakcije. Komunikacija s strežnikom poteka prek REST API-ja, kar omogoča sprotne posodobitve in upravljanje prek spletnega vmesnika. Rešitev je prilagodljiva in razširljiva, kar omogoča zadovoljevanje nenehno spreminjajočih se zahtev turistične industrije.
