System of data recollection, analysis and transfer by NFC for transport systems

This paper shows the development and test of a prototype that collects and analyzes data of cycling trips, such as position, distance, speed, and travel time. This device was made to provide an extra security layer to the data transfer in embedded systems. The raw information that is produced by the project described in this paper is highly valued, so there is a need to record and transfer data in a secure way between electronic devices. The solution proposed in this project was based on the Near Field Communication (NFC) protocol to make the communication stage from an Electronic Control Unit to NFC tags, and then, the information stored in the tags can be read from smartphones that have an NFC module inside them. The data was generated from a Global Position System (GPS) module and antenna using the Haversine formula to calculate the distance between two geographical points, this considering the earth as a sphere to minimize the error produced taking the earth as a plane surface. A functional device that includes extra security of the data transfer in cycling trips, through NFC technology was successfully developed, however, future implementations can be extrapolated to other areas, such as the transportation sector
