Beauty brand Sephora has placed smart tags at showcases in some of their shops. Scanning such tag with your smartphone would give you full information about the product and feedback of people who tried it. Another example of Sephora's digital technology use is a smart mirror that helps to choose cosmetics. This mirror is a big touch screen divided in two parts. One shows face of a user, another one provides list of different shades of products a buyer would like to try on. You only need to choose a shade, and 3D technology would give you a real time image with the chosen color on your face.
