摘要
As new authentic products are introduced into the market, counterfeiting has always been on the rise. In 2015, the global economic loss caused by counterfeiting is more than 1.7 trillion US dollars and has been increasing annually. Therefore, an inexpensive but efficient anti-counterfeiting platform must be developed to end counterfeiting. Here, a wireless platform for the anti-counterfeiting with an item-tracking is developed by integrating printed four key-device units, a 13.56 MHz rectenna (wireless power transmission), supercapacitors (power storage), 1-bit code generator chip (logic code), and an electrophoretic based quick response code (memory). Our near-field communication quick response code label platform is inexpensive and effective by utilizing blockchains and high throughput roll-to-roll printed devices. When practically applied, the near field communication quick response code label wirelessly operates through a near field communication carrier signal from a smartphone to demonstrate anti-cloning and authentic item-tracking through its interconnection with the blockchain.
