Implementación de un prototipo para la lectura y escritura de etiquetas basado en NFC (Near Field Connection) para el ingreso y salida de mercadería en la empresa Comsadimtelco S.A

Abstract

Abstract: The objective of this research was to implement a prototype for reading and writing labels based on NFC (Near Field Communication) for the entry and exit of merchandise in the company Comsadimtelco S.A. To do this, it began with the design and construction of the NFC device, which was programmed in the Arduino IDE software. The control of the device's functionality for sending data and management such as creation, reading, updating and deletion was done through a button and a visual indicator using an LED where the interaction of the device with the application is identified by color. In the development of the web application, PHP language was used with Laravel and integration with WebSocket, using the architectural design based on MVC. The database with MySQL allowed the management of data such as user registration, activation, product management, among others. Subsequently, the evaluation of the device and WebSocket server was carried out using a box test, where a satisfactory result was obtained, as well as the tests based on the heuristic method that showed acceptable management and functionality of the web system. It is concluded that both the NFC device and the web application, after pertinent adjustments, fulfill the established purpose and function correctly.
