In recent years, other investigations have emerged that seek to identify other alternative recognition patterns. This is the case of a project developed by a group of specialists from the University of Albany, in the USA, which is based on sweat.
They devised a device equipped with a system that identifies people by such secretions. The point is that perspiration contains a series of particular metabolites that serve to produce the identification of the individual.
In the first instance, the team takes data and makes measurements of these elements to establish a specific profile that is linked to a person.. Once this is done, the system will be able to identify the person taking that stored information.
In terms of biometric identification, we cannot fail to mention some innovative advances that are already a reality, such as the system for paying with the palm of your hand that Amazon launched a year and a half ago.
This option is already available in supermarkets, stadiums and other theaters in the United States. It is enough to bring the palm of the hand closer to the corresponding reader, without establishing contact, and in a few seconds the system recognizes the user, as well as the payment data linked to their profile, and the corresponding amount is charged.
