NFC tags, QR codes and other markers are easily connected to any internet content like a web page, a video, a contact page or any other content that you can identify with a URL as you would with a web browser.
Using the Sequence or Menu experiences, you can identify what content you want to connect.
You could think about it like sharing a link, so if you wanted to share a Youtube video, you would get the URL that you would use to share the video via e-mail or text and place that behind a Sequence and the video would be accessed with a tap of that group of tags.
Tapwow also offers Hand to Brand Experiences that provide more robust web functionality that can be added to Menus and Sequences.
