I decided to try this out myself in tasker, and got it working pretty well. It’ll simulate hardware key presses to type out the UID, followed by the enter key. The clipboard isn’t touched at all, although I did also include a version that copies to the clipboard then overwrites it with 40 other entries if you want to use that for whatever reason.
Only issue with this is that tasker doesn’t seem to be set up to handle every type of tag. For example, scanning my NExT works just fine, but my xM1 won’t open in tasker at all. Not a big deal, since I assume most people will be using an NTAG21X implant for this type of stuff anyways, but it’s something to think about.
I’m also working on a method to unlock the phone with NFC via tasker, but that’s being a pita to get working consistently.
