First I want to point out that I am a beginner with NFC tags. I use the NFC tools app and try to figure out what I can (and can't) do with the chip.
In the application there is an option for locking an NFC tag with password. Of course there is an option to remove the password making the chip available for writing. Let's say I want to have an NFC tag that is publicly available for everyone to read but locked with a password for write. With this application (NFC tools) what I can do to rewrite the data inside the tag is use one interaction to remove the password, another one for writing the data I want and a third interaction to lock the NFC again. My question is whether it is possible to do this with only one interaction? Maybe I have a mobile app that can make use of NFCs and the code behind can execute a procedure or a function that combines several instructions one after another. Does the NFC chip or protocol itself support this?
Single NFC interaction:
*hover the phone over NFC tag
remove password -> write data -> set password
*unhover
