I have been generating just such a QR code on my Android phone for a few months - to pass contact info to others. Works OK.
Not sure about the "referral" tracking bit - but I am probably not your typical user.
Lot of "prior art" using infra red signals from back in the early Windows mobile days - might be worth finding out where that went in the business environment - and thus potential paying customers.
