Modern entrepreneurship, in any sector, is characterized by a strong emphasis on the need for a continuous and accurate stream of data. This is not related solely to software-based products and companies, as the need for data can also refer to a number of Key Performance Indicators (KPI) and a lot of different information fundamental to the optimization of, for instance, manufacturing productive workflows. Different types of data can be provided by different instruments, but any company will involve a human resource, in the form of operators and/or users and customers, which means that people counters will always have an array of possible applications.
