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 a cheap passive RFID tag 2. secure verification of presence at a location, for example for couriers trying to deliver goods or security guards patrolling a space, without needing powered beacons, 3. shared ticketing for public transport, 4. some kind of geocaching application, where visiting a spot a

Flutter & Firebase authentication with streams and StreamBuilder

Sign up here for more videos: https://codingwithflutter.com/ GitHub code for this project: https://github.com/bizz84/coding-with-flutter-login-demo (or to follow along step-by-step: https://github.com/bizz84/coding-with-flutter-login-demo/releases/tag/update-gradle-and-flutter-1.2) This video is a continuation on my small series on how to build a login flow with Firebase. In this video I show how to use a special stream called onAuthStateChanged, and use it to simplify our widgets logic. This leads to a very elegant solution using StreamBuilder, which I highly recommend when using Firebase authentication.
