Under a NEDO contract, Dainippon printing is testing RFID tags on food and drinking products. RFID readers installed on the pricing shelf automatically read the electronic tag to identify the product whose consumption date is approaching, to the effect that cash discount will be carried out when purchasing the product, and advertisement of this product is automatically transmitted to the product shelf. In addition, the electronic tag checks whether a correct garbage box is used by the consumer for the package.
