What are the QR (Quick Response) codes have become an essential part of modern digital interaction, connecting the physical world with the virtual world quickly and efficiently. But do you know all the types of QR Codes that exist? Yes, there are different types, each with specific characteristics that serve different purposes.
Knowing these differences is essential to choosing the option that best suits each need and commercial strategy of your business.
In this article, we will explore the main types of QR codes , their functionalities and how to apply them strategically in different contexts.
What are QR codes?
Created in Japan in the 1990s, QR (Quick Response) codes store two-dimensional data in a matrix of pixels, allowing quick access dataset to information via mobile devices or specific scanners. With the advancement of technology, different variations of QR codes have emerged , each with its own characteristics.
Types of QR Codes
The main types of QR Code are: Model 1, Model 2, Micro QR Code, rMQR Code, SQRC, Fram QR. Below we will explain each of them.
QR Code Model 1 and Model 2
Model 1 was the first QR code format created. It a significant advance at the time, allowing data to be stored in a two-dimensional array.
However, the development when the connection is unstable of the Model 2 , an version, brought greater storage capacity, better error correction and greater flexibility in layout. Thus, the Model 2 became the current standard due to its efficiency and adaptability.
This format is widely used in advertising materials such as banners and flyers, where URLs are to redirect the audience to landing pages, digital profiles or online stores. It is also an ideal choice for digital business cards and other cases where it is necessary to store information, such as contact details or vCards.
QR Microcode
With the advancement of miniaturization and the to integrate QR Codes into increasingly smaller spaces, the Micro QR Code emerged . This compact version was to store small amounts of information, using less physical cell phone data space without compromising functionality.
Its use is common in packaging for small products, where printing space is . In the logistics sector, for example, it is in labels to identify products.
Similarly, in the area of IoT devices, it marks components with essential information for maintenance or tracking.
rMQR (Rectangular Micro QR) code
rMQR is an evolution of the Micro QR Code , introducing a rectangular matrix that expands flexibility for applications where the design or space layout does not accommodate traditional square shapes .
This innovation is especially useful in promotional materials and consumer electronics that require compact and discreet codes. In addition, rMQR is an interesting solution for virtual business cards with a horizontal design or printed materials that to optimize the use of space without losing the functionality of the QR code.
SQRC (Secure QR Code)
When security is a priority, SQRC comes into its own. This type of QR code is designed to protect sensitive information by allowing only or properly devices to access its content.
Its application is widely in business and financial environments, such as access control to restricted systems, distribution of confidential information in digital or physical documents, and even in banking and financial transactions.
Events and conferences also benefit from SQRC by using it to validate tickets or access credentials.
QR Code Frame
The QR Frame is a solution that combines functionality and aesthetics. It stands out for including a area in the center, where you can insert texts, logos or messages, keeping personalization as a priority.
