Scott:

Some of what you write is correct, some is wrong.
I'll make some comments below.

No, Cue Cat is not identical to QR codes at all.
QR codes are far more sophisticated than bar codes -
no comparison, not identical at all.

For that reason the QR code company is a success.

no: your statement only partially correct - partly wrong.

no. QR codes do much more than just conversion into an URL.

That's what you think. Can you give reasons? Have you ever tried it.

The reality is that QR codes are very well-suited and in great
use.

That is your personal choice, but not the choice of the Japanese market.

star and hash codes are not an alternative to QR codes. QR codes are
here to stay in Japan in addition to other ways of input. If your
hashcode method has merit it will coexist with QR codes. If it does
not have merit it will be replaced by something else - plenty of
alternatives to the hashcodes exist.

That needs a network connection. QR codes do not need a network
connection and are therefore much faster and much more versatile

You don't need any for QR codes.

Hope this helps,
