Traceability systems are very valuable to manufacturing companies, allowing to keep detailed records of its products history. The advent of Industry 4.0 further pushes this concept, integrating the Internet of Things into traceability by creating smart objects capable of communicating through the internet. RFID is the technology with the most potential for traceability due to its several advantages over technologies such as barcodes. The housings production line of Renault CACIA was used as the example of a shop oor on which to apply the proposed traceability system. This dissertation's system uses a cost e ective microchip, the ESP32, as the middleware that processes the messages exchanged with RFID Read/Write Modules, which are placed in several of the production line's stations. The Wi-Fi capabilities of ESP32 are also used to communicate the data with a server, which processes the data and performs queries to a MySQL database. This database was normalized, and applies speci cally to the housings production line, allowing to keep detailed records of every housing produced on the shop oor. A web graphical interface was developed, with its pages showing both real time data as well as historical production data. These web services can be accessed by any IoT device capable of accessing to the server. The developed solution showcases the viability of chips such as ESP32 to be integrated in RFID systems, allowing RFID readers and tags to be able to communicate through the internet
