Customers can take an electronic reader similar to a pen with them when shopping. When you want to buy food, smart labels can automatically tell you which vegetables and fruits are freshest, how much nutrition they have, where they are produced and how much they cost.

When you push the shopping cart past the supermarket checkout counter, the smart tag will automatically tell the cashier how much each item in the shopping cart needs to pay. When you take the food you bought home, the smart label will automatically design a menu for you through the computer at home, telling you the cooking method and the ingredients you need. When you pick up the medicine bottle, the smart label will also remind you of the dosage and times you should take.
