Controle de acesso por RFID gerenciado por aplicativo

Abstract

With the advancement of security technologies, electronic locks have been increasingly replacing manual models, offering greater convenience, control, and integration with smart systems. The application of the Internet of Things (IoT) in this context enables the combination of technologies such as RFID (Radio-Frequency Identification),Wi-Fi connectivity, and remote control via mobile application. However, this integration raises the overall cost compared to conventional locks, which offer only basic functionality.In this scenario, this work presents the development of an electronic lock control system that can be activated either by an RFID tag or through a mobile application. The app, developed using the Flutter framework, communicates with the ESP32 microcontroller, which is responsible for triggering the locking mechanism. Both components are integrated with Firebase, where an administrator manages authorized users through credentials. The system ensures secure access via password authentication in the app, while also allowing offline operation of the lock using a pre-registered RFID tag.
