NFC tags and processing

Hi guys,

I am thinking of making an app using Processing, but I want the app to be downloadable from an NFC tag. Is this possible? Has anyone done this that can lead me in the right direction?

Thanks in advance,
Grace

Downloadable … to what device / operating system? Android? Are you already able to program them with urls, like this? https://support.brickandmobile.com/hc/en-us/articles/203515080-Creating-Local-NFC-Tag-for-App-Download
