The Nordic packaging giant Reale, in cooperation with technology developers VTT Technologies and Panipol, launched an experiment in Finland: Printing RFID tag graphics directly onto the packaging without the use of silicon and transistors. The details of this experiment are kept confidential. Only the use of conductive polyaniline to print electronic patterns is known. This polyaniline material can generate memory elements. At present, the smart packaging that is being tested has the disadvantage that it can only store a small amount of data and cannot meet the requirements of Wal-Mart's RFID labeling on pallets, cartons or individual items. However, this technology still represents the future development trend. Just as printing bar code labels give way to conventional graphics that are directly printed on product packaging, RFID technology is moving in the same direction.
