Billboards are being developed that use facial recognition software and RFID technology to create tailor made ads to passers-by like those in the Tom Cruise film Minority Report.
Claims are specific targeting will eliminate unwanted messages. It would work through the use of RFID chips that have encoded information about an individual. As a person approached, the board would have access to person's buying profile.
According to Richard Gray in the UK Telegraph, "The billboards are being developed as part of IBM's Smarter Planet programme that aims to use technology to make people's lives easier and more efficient. Engineers in Japan have already developed a billboard that is capable of identifying a shopper's age and gender as they walk past to offer them products that are more accurately suited to them. The signs, developed by Japanese electronics company NEC, use basic facial recognition software and cameras to determine if someone is male or female and their rough age range before showing an advert that matches their demographic."See more here http://www.telegraph.co.uk/technology/news/7920057/Minority-Report-style-advertising-billboards-to-target-consumers.html
