Yes, I will correct you if you don't mind:
- QR-codes have nothing to do with Omron, QR (=quick response) codes
were developed by Toyota's subsidiary Denso, which formed a special
company called Denso-Wave which owns the QR code. They cost quite
a lot of work and money to develop. They were developed for
car parts management for Toyota cards - nothing to do with
mobile phones.
- There are many different 2D codes, not just QR codes. We have a
list of some common 2D codes in our QR code report:

but there are many more. If you feel like it you can develop
your own 2D bar code - but to develop a good one will take
many man-years, and a sound knowledge of practical mathematics,
and some optical engineering knowledge.
