RFID stands for "Radio Frequency Identification" and is a technology used to detect and track items, consolidating information in a cloud, by means of tags (labels) composed of a microchip, antenna, and internal memory. The reader activates the labels, which respond with information and characteristics of each product, in real time.
IoT stands for "Internet of Things" which, in short, aims to connect all things on the internet to generate data and information in order to provide benefits and new experiences for people in their work environment or personal life.
