Desarrollo de un sistema de comunicación con NFC para el acceso a información académica de los estudiantes de la FIE-ESPOCH.

Abstract

It was analyzed, implemented or designed a communication system using the near-field wireless technology (NFC), for access to academic information of students of the Faculty of Computer Science and Electronics FIE - ESPOCH. A comparative analysis of various alternatives and selection of best Arduino boards and then be engaged in the implementation technologies was established. The wireless communication channel between the devices primarily used the NDEF and LLCP protocols defined on ISO / IEC 18092 standards and the Institute of Electrical and Electronics Engineers (IEEE 802.2). Shield Ethernet that was responsible for sending and receiving IP frames required and Shield Adafruit PN532 for transmission: the design and subsequent implementation of an Arduino Mega 2560 that acted as a control center and processing, helping as an intermediary between the devices required and / or receipt of the request and subsequent submission of the application from the database to the Smartphone wirelessly; in addition he had a mobile application that contains a detailed list of all documents and / or files having assigned an identification number which was subsequently sent through technology to the shield NFC, being receipted and processed by the control device, which he made the respective request to the file server developed in the System Operational Database (MySQL) and displayed on a PC for verification and storage. The results indicated that the system has a high effectiveness rate of 72.84% compared to the traditional method. Thanks to the development of this system it was possible to expedite the processes used in each procedure performed, obtaining a secure and reliable real-time download. The installation of this Type of system and devices is highly recommended in educational institutions because of the great help, effectiveness and cost.
