Abstract
One of the main problems encountered in production processes is data acquisition on the factory floor. With the increase in production complexity, the amount of data to be collected increases. Currently, data are collected both manually and automatically. The manual collection involves documentation in a folder and storing in a separate room. However, there are other types of data that are automatically recorded into an information system. The data are registered and processed in different systems, which depend on the production stage in which the data are collected. The evolution of wireless technologies, such as wireless local area networks, sensor networks, and radiofrequency identification (RFID) systems, has favored the creation of mobile services related to the computing aspect. Therefore, this paper presents a model of the implementation of an electronic identification system based on RFID technology, for application in automatic traceability of products in a didactic manufacturing cell installed in the programmable logic controller (PLC) network laboratory of the São Paulo Institute, Brazil.

The Internet of Things (IoT) and Industry 4.0 have eliminated the need of an operator to be physically present in the production process
Radiofrequency identification (RFID) sensors allow a link to be established between a product and a tag, using an individual code that is connected to a database
A complete RFID system is composed of tags, which are fixed on the product, an antenna that interrogates the tags through a radiofrequency link, and a controller that interfaces with the computer and user [5]
Summary
The Internet of Things (IoT) and Industry 4.0 have eliminated the need of an operator to be physically present in the production process. Quality management is a major factor in the implementation of these new technologies [1], [2], [3]. Radiofrequency identification (RFID) sensors allow a link to be established between a product and a tag, using an individual code that is connected to a database. This code enables linking other information to the product, such as possible failures in its production, color, and size [4], [5]. Quality management through automatic retrieval of the product’s manufacturing history is needed; this can be realized by tag-recording of information such as location, product identification, and occurrences [4], [6].
