Desenvolvimento de um sistema para registro e controle de retirada de objetos em armários utilizando as tecnologias RFID e QR CODE

Abstract

An environment where many people have access to objects that are used constantly can generate a loss of control. In this way, some places where this process takes place use input and output control spreadsheets, normally made by hand, where the times of entry and exit of objects and who took them are recorded. Finding a way to do this control faster and smarter can improve the level of control by knowing who and what has been removed from a location, ensuring easy and streamlined entry and exit. The present work aimed to develop a system for recording and controlling objects using the following technologies: RFID (Radio Frequency Identification) for the identification of people who will have access to objects and the QR Code, that is, a bar code, two-dimensional, which is used to monitor the outputs and inputs of objects. The objects are stored in a closed environment in which access is only allowed by means of a card or key fob with a receiving antenna that captures the signal emitted by a radio frequency reader that is used to identify the person who has accessed the place. When removing the object, a camera checks if there is a QR Code, and if so, the system records the removal of the object in the name of the last person who gained access to the environment. In this way, as a result, the system with two modules, the RFID and the QR Code and the database in which the accesses to the cabinet and the removed objects are registered, can be visualized in the database with date and time of the events.
