QR codes have become integral to our digital lives, enabling quick and convenient access to information, promotions, and interactive experiences. However, there's more to QR codes than meets the eye. In this blog post, we'll explore various types of QR codes, including Model 1, Model 2, Micro, rMQR, SQRC, Frame QR, Static QR codes, and Dynamic QR codes, shedding light on their unique features and use cases.

Static QR Codes

When we think of QR codes, we typically think of Static QR codes. Static codes contain fixed information that does not change over time. Typically they are widely used for one-time purposes, such as providing a Wi-Fi login, sharing contact details, PDF menus, directing users to a specific website, or providing simple instructions.

Static QR codes are easily generated and require no maintenance or updates, but they lack flexibility. Once created and printed, static QR codes cannot be updated and have limited analytics and tracking capabilities compared to dynamic QR codes.

Dynamic QR Codes

In contrast to static QR codes, dynamic QR codes allow users to update and edit content in real time. With dynamic QR codes, changing the target URL, updating content, and tracking analytics are possible, providing greater flexibility for marketing campaigns and data management even after printing the QR codes.

Using dynamic QR codes, brands can frequently update their content, analyze campaign effectiveness, and track user interactions. The best uses for dynamic QR codes are physical products, packaging, marketing campaigns, assets, promotions, or situations where real-time data management is necessary.

The biggest challenge for using dynamic QR codes is that they require an internet connection to update and access the latest information.

SQRC (Secure Quick Response Code)

SQRC combines both traditional QR codes and RFID technology. Data is stored in the QR code and the embedded RFID chip. Applications requiring secure identification, such as access control systems, ticketing, and inventory management, use SQRC for anti-counterfeiting measures. However, like rMQR, SQRC requires specialized scanners.

Frame QR Codes

Frame QR codes include a customized frame or border around the QR code to enhance branding opportunities and make the code visually appealing. Use frame QR codes for marketing campaigns, product packaging, and event promotions.

However, devices may have difficulty decoding the frames or borders, impacting the codes' scannability.

Model 1 QR Codes

Model 1 is the OG QR code. The traditional black and white squares that we commonly encounter for restaurant menus. With a capacity of up to 7,089 numeric characters or 4,296 alphanumeric characters, Model 1 QR codes are versatile and widely used for marketing, advertising, and sharing information.

Model 2 QR Codes

As the name suggests, Model 2 is the upgraded version of the traditional QR codes. The most significant difference is that Model 2 QR codes provide additional security features and are more damage-resistant. Additionally, Model 2 codes can store more data than Model 1, making them suitable for applications requiring higher capacity and increased reliability, such as ticketing, inventory management, or situations where data integrity and robustness are crucial.

Micro QR Codes

Micro QR codes are smaller than Model 1 and Model 2 codes, making them ideal for packaging, flyers, and signage with limited space. Despite their smaller footprint, Micro QR codes can store up to 35 numeric or 21 alphanumeric characters. Typically Micro QR is used for electronic tickets, business cards, or small product labels.

While convenient for compact forms, its limited data storage hinders the amount of information you can share via the QR code and is more susceptible to error.


rMQR (Restricted Mode QR) is a QR code that restricts access to certain information, allowing only authorized users to decode it. It provides an added layer of security, making it suitable for applications where privacy is a concern. Industries that handle sensitive information, such as healthcare, finance, and government, use rMQR codes. Businesses can utilize them for confidential data applications, secure access control, or restricted information sharing.

The added security requires specialized software and systems, hindering convenience for users who require immediate access to the information.
