On iPhone, tapping an NFC tag with a URL opens a popup that allows you to navigate to that URL with a single click. If this URL is supported by an installed app, this app will handle this. For example, if you write a URL of a Spotify playlist onto your NFC tag/sticker (which you can also do from the phone via an app like NFC Tools), then bring that sticker to iPhone, it will show this as a Spotify URL, and you can tap on this notification and go to that Spotify playlist. So all you need to experiment with is a writable NFC tag and your phone, no other hardware required. I bet Android phones offer a similar experience.
