How to encode a nano payment request into an NFC tag
This video is a short demonstration of how to encode a nano payment request for a specific amount into the URI of an NFC tag.
The URI should be:
nano:{RECEIVE_ADDRESS}?amount={AMOUNT_IN_RAW}
Removing the ?amount= section allows you to initialize a transaction without a specific payment amount.
In this demonstration, it show how easy it is to encode a transaction to create NFC-based payment applications.
The NFC tag is an NTAG215, which costs 40 cents. But any will probably work.

The Natrium wallet is not available through F-Droid, but it can be installed directly from GitHub: https://github.com/appditto/natrium_wallet...
The purpose of this video is to show you how to encode the nano transaction into the URI. For a real-world application, you will need to protect the NFC tag such that the information it holds cannot be easily over-written by a malicious actor.
