Aplicação de RFID e NODEJS para controle de acesso

Abstract

Companies have environments shared by several employees, and often these employees share resources such as equipment and computers. In order to avoid material losses, these resources need to be protected from misuse. However, conventional protection methods such as mechanical keys or biometrics can be simple or expensive, making them inconvenient or inaccessible for small and medium-sized companies. Thus, in view of the difficulty of current solutions in solving the problem in question, the study and development of a flexible and low-cost system for access control is justified. The work aims to develop an embedded system that allows the control and logging of access, as well as a web interface for consultations. Using technologies like ESP32, RFID and NodeJS, a system was developed in hardware and software capable of identifying tags and RFID cards and activating a solenoid if the user has allowed access. The developed system was able to meet the proposed objectives and remain competitive in the market, both in terms of speed of activation and cost.
