Data and error correcting code are arranged as shown below. Sample: Version 2 of Model 2 with level M A mask is applied to the code to prevent the same pattern with the position detection pattern from appearing. They have different features and data capacities. A larger version contains greater data. The actual size of the code increases as well. The standard version is 21 x 21 modules MicroQR has 11 x 11 modules , and as version increases, 4 modules 2 modules for MicroQR are added on each side.
Model 1 is the prototype of Model 2 and Micro QR. When a version increases, 4 modules are added to the code in both the X and Y directions.
Model 2 has an alignment pattern for better position adjustment and contains greater data than Model 1. The version 40 can contain up to numeric characters.

Whether it is upside down or at an angle, a QR code will be read by a scanner perfectly and without error. This saves time when there is the need to scan a number of items.

It can be placed on magazines, flyers, and posters. Locations that are prone to creases, damage, and tampering. Yet, a QR code will still be able to perform its intended purpose because of its error correction capability.
Error correction is the capacity of a QR code reader to reconstruct damaged or missing information on a QR code. It is able to do this because a QR code is a pattern that can be easily recreated with an algorithm. However, this is limited to QR codes with a lower number of squares or QR code data size. Whether it may be a scratch, missing data from a rip, stain, or a mark, a QR code can still be scanned perfectly fine. It is not a fragile image that can fail unexpectedly, making it quite reliable.
Related: An overview of QR code error correction feature. A QR code is composed of two colors, one for the black pixels and the other for the white ones. Different print mediums such as flyers and posters tend to discolor through time as it gets exposed to the elements.
Despite the change in colors, the QR code will still be able to function as it is intended. Avoid these. Unlike barcodes that need to be scanned at a close range, QR codes can be read no matter how far it is. As a result, QR codes can be placed almost anywhere without question on whether or not they can be accessed by scanners. If a QR Code contains a lot of data, then you will generally see that it looks "busier" to the naked eye more modules and generally more tightly packed together.
Here are some examples that show the difference in appearance for codes holding different volumes of data:. In addition to storing the actual data a user wishes to save, the QR Code must also store other data that forms the framework of QR Codes. This includes positioning, timing, alignment and format data as well as error correction and version data. All of this data when combined ensures a QR Code can be read easily by a wide range of scanners.
Thankfully most of the QR Codes basic framework doesn't subtract from the volume of data it can store, except for Error Correction. Error Correction is available at multiple levels and the higher the level of error correction you apple, the less data you can save in the QR Code.
