A future article: Scientists have discovered a technique that allows identification of a person using only the advanced technology you likely already carry with you, and which is not affected by the ambient electromagnetic interference that is omnipresent in our technological society. It allows tracking a person from room to room with a near-perfect degree of accuracy, provided that each room is irradiated between approximately 380 and 700 nanometers. The technique begins to falter outside of this range, so it's not perfect. However, it has been shown to be able to distinguish a person from others even in crowded areas, which opens up a plethora of heretofore untapped potential.
As an added bonus, we are all carrying a pair of electromagnetic receivers that can directly detect this range of the electromagnetic spectrum, so this technique is very cheap and highly cost effective. We tend to reflexively keep these receivers turned off, so it may take some adjustment to your daily routine before you start noticing the benefits of keeping them activated, but scientists confirm that it takes very little practice before keeping them always-on becomes routine.
