Digital signage system emits aromas to attract customers

Japanese Tech powerhouses NTT Communications and Recruit developed a digital signage system capable of simultaneously emitting scents and showing compatible commercials. A prototype is currently being tested in an underground shopping mall in Tokyo.

The idea is to get passery-by to walk into a cafe or buy a certain product by not only showing them video ads but also by by appealing to one’s sense of smell.

Once you are hooked, you can grab a discount coupon from a box located just below the 42-inch LCD display and redeem it in all stores and eateries participating in the test run.
