NEC Corp. has "designed a method for digital signs to track the age, gender and number of pedestrians that walk by them... NEC sells flat-panel monitors that display ads, commonly found in stores, airports and other heavily trafficked public areas. It also provides the software to manage and distribute advertising content to those screens... The company embeds a camera into the monitor, allowing it to constantly film people walking by. NEC takes that footage and applies a program that can automatically scan each person's face, calculating the individual's rough age and gender. While not accurate to the year, the program is fairly good at placing a person within a 10-year range."
