From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Exactly. No matter the y dimension. Barcode data is only stored in x. Whereas QR uses x and y for data.
They also use the corner squares and a few specific dots to allow scanning from greater angles. Basically allowing the data to be read in 3d space. Even though only 2d is used to store that data.
This is why QR can work well with cameras. Whereas bar codes are designed for very short range laser reflection.
PS lots of info on QR online including open source programs to make your own.
The same goes for bar codes. But readers involve some very simple maker skills. Making simple barcode readers was a common school science project in the early 90s.
