Unlike traditional barcodes, QR codes support a comprehensive error correction feature, unlike its counterpart.
In the digital era, committing a mistake in the business industry can make companies lose millions in profits. Because of that, marketers are looking for a digital marketing solution that lessens the errors it makes, especially in choosing a data storing tool like barcodes.
Since it is a challenge for them to identify what kind of barcodes have a built-in error correction system, QR code experts introduce the QR code technology.
Thanks to Irving Reed and Gustave Solomon’s Reed-Solomon error-correction algorithm, QR codes can still be scanned even if it gets dirty or worn-out.
Because of that, the information a person store in a QR code is secure and useful for a long time.
As long as the content like a URL doesn’t expire or get redirected to another domain, there will be no problem.
Just like in any technological advancement, understanding how it functions becomes a part of a person’s technological learning.
If you want to learn more about how the QR code’s error correction feature works, here are the following concepts.
How does the QR code error correction feature work?
The error correction feature works through the use of the Reed-Solomon error-correcting algorithm to the original data.
This error-correcting algorithm works by duplicating the original data for optimal scanning capability.
This way, it will still be scannable even if the QR code experience a tear or damage due to extreme weathering conditions.
Before the Reed-Solomon error-correcting algorithm is used for technologies such as CDs and DVDs.
This kind of code measures against the communication noise created by artificial satellites and planetary probes. CD and DVD manufacturers use this code to correct data at the byte level and other burst errors.
With a different kind of tear or damage, here are the following error correction levels that a QR code can have. Starting from Level L to Level H.
This is the lowest level of error correction rate that a QR code can have. QR code software uses this level if the user intends to generate a less dense QR code image.
Level L has the highest error correction rate of approximately seven percent (7%).
Level M is the middle tier of the error correction level that QR code experts recommend for marketing use. Because of this, marketers can correct their QR codes at a medium level. Level M has the highest error correction rate of approximately fifteen percent (15%).
This level is the second to the highest error correction level. This error correction level has the highest error correction rate of approximately twenty-five percent (25%).
Level H is the highest error correction level that can withstand an extreme level of damage in their QR code. The level Q and H error correction levels are most recommended for industrial and manufacturing companies.
These codes can experience both environmental and man-made conditions that lead to inevitable damages. This level has the highest error correction rate of approximately thirty percent (30%).
By knowing these following levels, you can spot the QR code’s error correction level without the need of running decoding software. You can spot these levels by looking at the following symbols on the codes.
How to spot these error correction levels?
There are four different error correction level symbols that you can view on these black and checkered boxes.
These symbols can let you determine what kind of QR code is being generated by a user.
These level symbols are as follows. Here are the following ways how to spot them.
1. View a copy of your QR code and look for its error correction area.
The first step to do when looking at its error correction area is to find a QR code that you can find in your room.
These codes can be found in your electronics or gadgets. Once you have found one, look at the bottom left portion of the code beside the lower eye.
That bottom left portion code beside the bottom eye is the area where you can view its error correction rate.
2. Know what level of error correction does it has.
Once you have located the error correction area, you can determine the level of error correction it has by looking at its code nature.
If the code is fully shaded, the level of it is level L. When the code is shaded halfway at the bottom, it has level M. If it is halfway shaded at the upper area, then it has a level Q error correction rate.
Lastly, when the code at the bottom left portion beside the lower eye is not visible, then it has the highest error correction level which is level H.
3. Test generate a QR code and decide which QR code generator has a high error correction level.
The best way to generate a QR code that offers safe and secure QR codes is by looking for the best QR code generator that generates QR codes with a high error correction level.
Through this, you will ensure that the QR code generator you are using provides safe and secure QR codes for your personal, industrial, and manufacturing use.
One of the known QR code generators that creates QR codes with a level H error correction rate is QRTIGER. QRTIGER is a safe and trusted reliable QR code generator.
With its ad-free and easy-to-use interface, users can get through their QR code generating securely and easily.
Benefits of looking at a QR code’s error correction area
To know the QR code’s purpose for usage
One of its benefits is to know its purpose of usage. In this way, people will know what error correction rate the QR code is intended to be protected with.
Through this, they can distinguish if that QR code is made for personal, marketing, or industrial use.
Measure its damage-resistance
By looking at the code’s error correction area, people can determine and measure its resistance to any damage or dirt.
Because of this, companies and marketers can save funds by choosing the right error correction feature that they want to implement in their QR codes.
Enable users to save money
As companies and marketers know what code error correction feature they want to add to their QR code, the money they spend for a long-term marketing campaign is saved. Because of that, they can save money and resources for the future.
Saves the environment
The error correction feature helps marketers and companies to save money and resources. Because of that, they will no longer need to print more QR codes as they can withstand any damage.
Through the use of it, they can reduce paper usage and help save the environment.
Educate people about how QR code error correction works
If you are a technology-loving person and you want to share your knowledge about trivial tech like QR codes, the use of locating its miracle in correcting errors can help enlighten people.
Because of this, they can increase other people’s knowledge about it and become a QR code expert along the process.
Through this, people can understand what QR code error correction generator they want to use in generating these codes.
QR code error correction – saves and secures information at best
Today, tech individuals use to improve and enhance the QR code’s structure to secure its scan-ability capability. Because of that, one of the features they improve is its error correction capability.
Through this, the users can generate their QR codes without having to worry about any scanning errors.
