title: password on nfc tag?
body: <p>I am looking to implement nfc tags on some of my sites with general information text written to the tags. The catch is I only want certain people to be able to read the tag. So in a way I would like the user to scan the tag and be prompted for a password before being able to read the tag. Is this possible ? Open to any ideas as long as the tag can hold enough text approx 300-400 characters. Thanks in advance for any info.</p>
