Created by Australian-based start-up of the same name, Sharetapes are physical cards that you can load with playlists from YouTube, Spotify,  8tracks and more. You can then share your playlist on other people’s smartphones via near-field communication (NFC) technology or quick response (QR codes) scanning codes.

To play your tape, either tap with NFC (recent Android, Windows and Blackberry devices) or scan with a QR code reader (iPhones and non-NFC devices).

It is too bad that the  example code is only a number and not a YouTube video about the product.
