We use NFC Tools Pro for writing to tags. It lets you manage lists of records and write multiple records to the tag. It’s also pretty good for reading tags.
We use NXP TagInfo a lot, it’s great for getting all the data out of tags, eg. doing full memory dumps. Good for debugging things.
First thing tho before you do anything else, is to use the Dangerous Things app to ‘secure’ the tag. Don’t use any other apps to set passwords etc as they’ve all got some issues. IMHO.
Have fun!
