The banking sector is especially open to adopt novel technologies capable of automating and accelerating processes for person identification. The aim is twofold. On the one hand, it is interesting to authenticate their customers, not only at the time of carrying out bank operations, but also the very moment they enter an office, using either whitelists or blacklists. On the other hand, it is useful to access the profile of the visitors and count the daily number of customers in an office, in order to optimize the resources and personnel of the workplace. In this sense, facial recognition is one of the least invasive and more generally accepted technologies.
