Thanks Gerhard,
I knew the Denso Wave part, but didn't know the differences between QR
and 2D. Thank you for the clarification and insights. Very much
appreciated.
Does anyone on this list have any actual usage data of QR codes in
Japan? We are seeing them everywhere and on virtually everything (even
the bag of kitchen salt we bought this past week had one on it), but are
they being used? Is there any data about this publicly available?
