演題： “Prospects in R2R gravure printed electronic devices for authentication”
Abstract:
As globalization in trading and online shopping become normal life to everyone via a smartphone, the counterfeit issue has been surged in high as well. Because of counterfeit goods and forged products, the estimated social cost was globally about $700 billion annually in 2012. That’s why anti-counterfeiting and authentication technologies have been developed based on the cost of the protection versus the value of the protected products. Therefore, up to present, there is no general anti-counterfeit technology that can apply from the high value added to the low value added products with a high security.
In this presentation, for the first time, the general anti-counterfeit technology was demonstrated by implementing an advanced additive technology such as a roll-to-roll gravure for manufacturing inexpensive Near Field Communication (NFC) cryptogram-label, generate codes with a designed frequency (0.1 to 30 Hz) via smartphone tagging and consequently connected to a blockchain to bring all information about the target product to the individual’s smartphone or do transaction to add data as an authentic ID. Since the printed NFC activated cryptogram-label cannot be easily duplicated, it can be used as the general anti-counterfeit technology with the high security by interconnecting with the blockchain technology.
