After writing a URL, for example, your NFC tag can be left intentionally in a place easy to reach for everyone.
For this purpose, you can lock your NFC tag so no one will be able to
change the information on it. But be careful because this operation
can't be undone, even by you.
An alternative option is to set a password protection. It's useful
because it avoids a definitive lock of your NFC tag and prevents writing
if the password hasn't been removed before.
Rather practical, right?
