It is feasible to make QR codes in a wide range of shapes and styles; however, five types are generally found. They all do similar work; they simply look marginally different.
- QR code: This is the first form of the QR code made by Denso Wave during the 1990s. It's not difficult to recognise by its three locater designs in the base left, upper left, and upper right corners.
- Aztec code: while it seems to be like a QR code, the Aztec code, created by Welch Allyn, contains just a single locater design, directly in the center.
- Maxi code: This sort of QR code is utilised by the US postal service. It's like the Aztec code in that it puts the locater design in the center, yet it utilises a honeycomb design rather than squares.
- PDF417: Designed in 1991 by Ynjiun Wang of Image Advancements, the strangely named PDF417 originated three years before the QR code. It seems to be a blend between a QR code and a barcode and is effectively conspicuous by its rectangular shape.
- Semacode: Created by a software organisation of a similar name, the Semacode is a data lattice that seems to be a conventional QR code yet doesn't have unmistakable locater designs.

How do QR codes work?
The examples inside QR codes address parallel codes that can be deciphered to uncover the code's data.
A QR peruser can distinguish a standard QR code in view of the three enormous squares outside the QR code. Whenever it has recognised these three shapes, it realises that all that is contained inside the square is a QR code.
The QR code peruser then investigates the QR code by separating the entire thing into a lattice. It takes a gander at the singular lattice squares and relegates every one a value in light of whether it is dark or white. It then bunches network squares to make bigger examples.
How would I examine QR codes?
Most cell phones have underlying QR scanners, which are in some cases built into the camera. A QR scanner is just a method for examining QR codes. A few tablets, like the Macintosh iPad, have QR readers incorporated into their cameras.
A few more seasoned gadgets might require a specific application to peruse QR codes; these applications are promptly accessible on the Apple Application Store and Google Play.
