For several years, marketers in Japan have been placing barcodes on billboards and magazine pages and using them to blitz ads right to mobile phones.
The barcodes act as sort of a nerve center, storing a wealth of material a marketer can send right to a handset once a consumer scans it with a camera phone.

The barcodes donâ€™t look like the ones used in the supermarket â€" more like a crazy maze.
