Run tasker task on my phone, and Rickroll others

Sure: simply use the chip’s ID in your custom tasker script.

Here for example is how I use my flexM1 as a token to unlock my banking app with Tasker. The flexM1 is normally used to unlock my house’s front door. But if I scan it on my phone, the Tasker script picks up the UID, does some math on it and extracts my banking app’s PIN from it:

You can also get Tasker to read the content of the tag and do things with it. I suppose in your case, if it finds “Astley” somewhere in the URI, it can do special actions or something.
