My first project with QR codes.
It’s a very promising technology and it’s huge in Japan – driven there by smart phones that can read them.
I’ve done many projects using the old-style picket-fence barcodes. Printing barcodes on letters, envelopes, pallet labels, work tickets, sticky labels. And scanning them in warehouse and retail applications.
QR codes may have an even brighter future if and when the readers become ubiquitous (like in Japan) and then all kinds of novel uses will magically appear.
