RPC: It does not need a barcode, but I have seen it done with a barcode-like symbol included. Augmented reality uses GPS + feature recognition technology. Hm. Feature Recognition. What are the name of the patents we licensed from Scanbuy?
AR is definitely a competitive technology that mobile barcode pros are keeping an eye on. We tell each other it won't work because it is impossible to monetize. However, companies like Google, Yahoo and Microsoft tend to follow the technology and worry about the business case later.
