What is a QR Code?

QR code stands for "Quick Response" code — a registered brand of Denso Wave, invented in 1994.

A QR code is a two-dimensional barcode that stores different information to be shared publicly. It enables quick access to data like websites, contact details, or actions without manual input.

The QR Code is readable by computers (having a webcam), smartphones, and tablets. In a single QR code, you can encode 4296 characters. However, once it is generated, you cannot alter it. If you attempt to change a code, it will result in a different QR code being produced.

The QR code consists of black squares with various vague patterns organized in a square grid on a white background. The data is extracted from those fuzzy patterns.

It uses four standardized encoding modes.

• Numeric
• Alphanumeric
• byte/binary
• Kanji

The QR code generation is divided into 2 types: Static QR codes and Dynamic QR Codes.

Static QR Codes vs Dynamic QR Codes

Static QR Codes contain fixed information encoded directly into the code and cannot be modified after creation. Furthermore, it does not enable you to track the scans' data and only leads you to one URL. The static QR codes are only helpful for personal use and branding. They are not beneficial for business use because of their limitations.

On the other hand, you can change the dynamic QR codes. Dynamic QR Codes allow for editable content, enabling updates and changes to the encoded information even after the code has been generated. For marketing purposes, dynamic QR codes are more valuable.

You can track the QR code and track the number of scans. When the user scans the QR, you can track the scan location (city, country) and the user's device type (Android, iPhone).

Both types of QR codes possess a major difference according to their usage. Static QR codes are more in use by the audience comparatively as they are free to use, and any QR code creator can help you create them. At the same time, dynamic QR codes are comparatively an advancement in the QR codes. You can alter your QR images even after creation.

But the question is, can you switch from a static to a dynamic QR code?

The answer is NO. Once the static QR code is created, you cannot switch it to a dynamic one. The static and dynamic QR codes are pretty different from each other.

Use cases of QR codes.

Many creative ideas exist on how businesses, municipalities, and non-profit organizations can use QR codes to market and communicate better to their stakeholders.

• In business conferences, you have to engage and communicate with a crowd. If you utilize QR codes on your counter or station, interested persons can scan that code and receive your business details.
• Scanning the QR code helps in sending the message. The customer can only receive the message once it scans the code. It's helpful in SMS marketing.
• QR code helps you read the newsletters, email marketing, and monitor your email's performance rates. The user can also continue reading the email on its mobile phone by scanning the QR code. In this way, your email will be accessible on any platform.
• Scanning the QR code leads the customers to the landing page or the app's download page and start downloading.
• Scanning the QR code helps the website visitors view your business location and give specific directions to your business location.
• Scanning the QR code leads the customers to your social media business pages.
• The most prominent use of QR codes is in shopping and e-commerce websites. The customers can scan the QR codes for the discounts and promos.
• The banks are using the QR code on their debit cards, and several countries are utilizing it for their identification cards.

What is the Error correction level in the QR Code?

Error correction level in QR Code means the capability to restore data if the QR code gets dirty or damaged. It's measured in percentage (%) for every code. That shows the percentage (%) portion of the QR code (excluding the corners). If it gets removed or damaged, the QR code remains in working condition.

Several factors, such as the operating environment and QR Code size need to be focused on selecting the error correction level.

The users have to choose from the four error correction levels.

Select Level L (7%) for a clean environment with a large amount of data. Typically, Level M (15%) is frequently used.

Select the level H (30%) or Q (25%) for the factory environment where QR codes get dirty.

What if my QR Code is not working?

QR Code has many limitations. It sometimes does not work due to various reasons given below:

• Check your entered data: Sometimes, minor typos in your URL break your QR code.
• QR Code Quality: Check if the QR code has been damaged, distorted, or printed poorly. Sometimes, low-quality printing or damage to the code can make it unreadable.
• QR Scanner Issue: Check your code into another QR Scanner just to verify that the issue is with the tool or with your code. Many times, the QR scanning apps need to be fixed.
• Contrast Issue: Make sure there is sufficient contrast between your background and the foreground of the QR code. The foreground must always be darker than the background.

FAQs

What is mobile tagging?

It is the process of putting the QR code on some real-world object, marking it with some message or content, or connecting it to some landing page. A smartphone can decode/read the QR code with the help of a camera.

Which is better, barcode or QR code?

The barcode is single-dimensional. That means you can scan the barcode in a line. In contrast, the QR code is two-dimensional and can be read both vertically and horizontally. In QR codes, the information can be encrypted, which makes it more secure than barcodes.

How many times can my QR code be scanned?

The generated QR codes are static, will work forever, and will not get expired. The only condition is that you can't edit the QR code again.

Can a Wifi QR code be dynamic?

No, the Wifi QR code needs to be static. Because when the user scans the code, it has no internet connection. For a dynamic one, the user has to be connected to the internet.
