QR Code Model 1 and Model 2
Model 1 is the original QR Code. The largest version of this code is 14 (73 x 73 modules), which is capable of storing up to 1,167 numerals.
Model 2 is an improvement on Model 1 with the largest version being 40 (177 x 177 modules), which is capable of storing up to 7,089 numerals. Today, the term QR Code usually refers to this type.
Micro QR Code
Only one orientation detecting pattern is required for this code, making it possible to print it in a smaller space than before.
This code can be viable even if the width of its margin is 2 module-worth (QR Code requires a margin of 4 module-worth at least around it). The largest version of this code is M4 (17 x 17 modules), which can store up to 35 numerals.
iQR Code
Code that can be generated with either square modules or rectangular ones. Can be printed as a turned-over code, black-and-white inversion code or dot pattern code (direct part marking). The maximum version can theoretically be 61 (422 x 422 modules), which can store about 40,000 numerals
This code can be printed as a rectangular code, turned-over code, black-and-white inversion code or dot pattern code (direct part marking) as well, allowing a wide range of applications in various areas.
SQRC
QR Code that has a reading restricting function. Can be used to store private information or manage a company’s internal information), Its appearance is no different from the regular QR Code.
This code can be printed as a rectangular code, turned-over code, black-and-white inversion code or dot pattern code (direct part marking) as well, allowing a wide range of applications in various areas.
Framed QR
Since letters and images can be inserted inside the canvas area, FrameQR can be used for promotion, authenticity judgment, and other various uses.
FrameQR is a QR code with a “canvas area” that can be flexibly used. In the center of this code is the canvas area, where graphics, letters, and more can be flexibly arranged, making it possible to lay out the code without losing the design of illustrations, photos, etc.
