Printed Four Key‐Device Units for Unified Platform of Wireless Anti‐Counterfeiting Label to Bridge in Blockchain

Abstract

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.

“…[158] However, the usual method of combining printing techniques that utilize similar layer thicknesses is a direct print of layers one-by-one, sometimes with an interlayer, to avoid material mixing. [159] The right choice of technique and material allows printed electronics techniques to be used in unusual applications, e.g., to make functional electrical connections on temperature-sensitive surfaces [160] or to produce structures with temperature-sensitive geometries. [161] Application area of printed electronics includes but is not limited to displays, [162][163][164] sensors, [165][166][167] electronic components, [168,169] and wearables.…”

“…Fully printed rectennas can be used in various applications, e.g., a smart packaging or biosensor. Sun et al [159] gravureprinted the anticounterfeiting label integrating printed four keydevice units, a 13.56 MHz rectenna, supercapacitors, a 1-bit code generator chip, and quick response code. The R2R printing process was performed in a cleanroom at 6 m min −1 speed, followed by curing at 150 °C.…”

Integrating biopolymer design with physical unclonable functions for anticounterfeiting and product traceability in agriculture

“…Counterfeiting has been a global, long-lasting, and unsolved issue that permeates virtually every field of our society from the luxury goods industry to pharmaceuticals. Over the years, various anticounterfeiting strategies including holography ( 1 , 2 ), watermarks ( 3 , 4 ), barcodes ( 5 , 6 ), quick response codes ( 7 , 8 ), and radio frequency identification (RFID) tags ( 9 , 10 ) have been developed, offering competitive countermeasures against growing fraudulent practices worldwide. Many of these anticounterfeiting technologies, however, are based on deterministic encoding mechanism that has inherent vulnerability to various cloning attacks.…”
