A Japanese Company has manufactured a vending machine that uses facial recignition to recommend a drink for the person standing in front of it. There is already a working model placed at a Tokyo train station and more are projected to be placed in Japan.
There are sensors in the machine that detects a persons gender and age. Going through a computer system, it will make a recommendation for what type of beverage that person is most likely to enjoy. A data that includes suggested products for certain type of person in addition to the temperature of the environment and time of day will ensure a sale and a happy customer!
