Supply chain, blockchain, and linking the real to the digital.

The last video (for now) on blockchain and supply chain.

A final piece of the puzzle is to irrefutably link the physical objects and participants to their digital representations on the blockchain (tokens and wallets). This is especially tricky in open blockchains, where authentication becomes extremely important.

I know of four main ways:

* physical unclonable functions

* QR codes

* RFID tags

* IoT devices

I discuss each of these in terms of its strengths and weaknesses, which are usually...

Follow up from initial test reading RFID tags in a wallet. These tests were using the xPortal as before with Monza 4 powered RFID tags. This shows how passive RFID can be used to monitor secure facilities or a customer loyalty program.

Do you have use cases for cheap passive RFID tags that can one-way authenticate?

I'm asking for help from my connections to come up with concrete uses for a cheap passive RFID tag that can perform one-way authentication.

Those of you who follow my videos will know that recently I invented and filed a patent for a blockchain-backed enhancement for such a thing. So far I have:

1. replace barcodes with a more secure RFID in open supply chains so anyone can report goods in transit, not just trusted partners,

2. replace IoT devices currently used to track expensive goods with...

RFID Weapons and Firearms Tracking - ODIN's Patrick Sweeney

http://odinrfid.com/rfid-weapons-tracking

Radio Frequency Identification (RFID) is a breakthrough technology for tracking weapons, small arms and firearms. RFID Tags and RFID readers can be used to gain 100% visibility and accountability into where and when a firearm moves within a facility or vehicle. This short video shows how using teh US Department of Defenses ISO 18000-6 passive RFID standard can increase security and accountability of weapons. Passive RFID is not bringing a new world...

Chipless RFID System for Low Cost Item Tracking - Stevan Preradovic

This seminar was presented on 14th January 2009 by Stevan Preradovic, a PhD candidate at the ECSE Department at Monash University, Australia. Stevan presents his PhD research work on a novel chipless RFID system based on multiresonators which is intended for tagging low cost items such as banknotes.

Abstract - A fully passive, printable chipless RFID system is presented. The chipless tag uses the amplitude and phase of the spectral signature of a multiresonator circuit and provides 1:1...
