bravo22, Kevin from intelliPaper here. GREAT point. (and if you have a link the 5 cent NFC tags, I'd love to see it...) "Why the USB part?" Because it is ubiquitous, and easy to use. While there are aspects of what SwivelCard offers that does do not rely on USB - Consider if an audience does not have a QR or NFC reader. Sure, you can print a unique URL on the artwork and encourage them to type it in... Conversations will increase in value if there are easy ways of extending them in a meaningful way. This is what SwivelCard is about. For a person looking to extend a valuable conversation, the ROI on SwivelCard is very high.
