Since you got all the password protection working, you’re free to write whatever information you want to the tag. I’ve been meaning to write a short guide for writing to the tag using the TagWriter tool. Here’s a demo of writing a web address to your tag:
Main screen. Select “Write tags”
Select “New Dataset”
There are many options. Select “Link”
Paste whatever URL you want to link to in the second field “Enter URI data”. Select “SAVE & WRITE”
Select your write options (I chose none.) Select “WRITE”
Hold the phone against the tag to write the info. Orientation is critical for this steps. You’ll have to wiggle it around quite a bit on the back of the phone the first time to find the correct spot. The xLED tester really helps.
You’re done! The information has been written to your tag and it should attempt to open in the browser when you scan the tag outside of TagWriter. The first time you’ll have to select your “Default Application” for NFC tags, but after that it’s automatic.
