I found a method to use NFC on Android even when screen is turned off.
I didn’t test it, but maybe someone want to give it a try.
This can be used to open an App, or even to open a Form in an App and prefil it. Even if the App is not opened.

You can do that when saving this kind of value to your NFC tag… this is a formula in virtual column which is converting the existing Key column’s value for you tag.
