QR codes are seen almost everywhere these days. From menus and boarding tickets to payment links and product pages, they provide quick access to a variety of services and information.

Untrained eyes may not distinguish between the various kinds of scanner QR codes and other two-dimensional barcodes. But there's always more to a story than meets the eye.

Only a QR code scanner can decipher the alphanumeric data hidden within each pixel and QR code pattern. Additionally, each code's pixels and modules will vary based on the length and type of characters embedded in it.

To learn more about QR codes, keep reading the article. It will provide you with fundamental knowledge about QR codes, how they work, and their types.

What exactly are scanner QR codes?

A QR code, short for Quick Response code, is an array of black and white pixels set in a grid, which stores data for a machine to read. These codes are often used in marketing and advertising campaigns and to track information about products in a supply chain. Additionally, they can also be used to share links to websites, contact information, or make payments.

A QR code scanner is a software or device designed to interpret and decode QR codes. It uses a device's camera or specialised hardware to capture the QR code's image, analyse it, and extract the encoded information.

How do QR codes work?

Information is encoded into QR codes by combining data, patterns, and shapes. The decoding software analyses the pattern and extracts the contained data when a mobile device, or any other QR scanner device, scans the code. The data can be anything from a simple website URL to a complex set of instructions.

Modern mobile devices have built-in QR scanning capabilities as a result of technological improvements, which makes it effortless for end-users to access the data contained in the codes. Besides, there are also standalone QR code scanner apps available for download on various platforms.

What are the different types of QR codes?

  1. Static QR codes: As the name suggests - Static, these QR codes contain fixed information encoded within them. They are suitable for scenarios where the content doesn't change frequently, such as linking to a website's homepage or providing contact information.
  2. Dynamic QR codes: Such QR codes allow for the modification of their content even after creation and distribution. This flexibility makes them ideal for applications where updates or changes may be necessary, such as event promotions or product inventory tracking.
  3. Secure QR codes: These QR codes incorporate additional layers of encryption or authentication to prevent unauthorised access or tampering. They are commonly used for sensitive applications like payment transactions or secure document sharing.
  4. Custom QR codes: Such QR codes feature design elements or branding overlays, making them visually appealing while retaining functionality. They are popular in marketing campaigns and branding initiatives, where aesthetics play a crucial role in attracting and engaging users.

Check the table below for a better understanding of these codes:

Examples Marketing campaigns, event registrations Contact information, website links Secure payments, confidential document sharing Branding, promotional materials, loyalty programs

What are the types of QR scanners?

There are several types of QR scanners available, each with its own features and capabilities. Here are some common types:

  1. Mobile apps: These are smartphone applications that utilise the device's camera for scanning QR codes. Examples include apps like QR Code Reader, Barcode Scanner, and Google Lens.
  2. Built-in camera functionality: Many smartphones now come with built-in QR code scanning functionality as part of their native camera apps. You can simply point your camera at a QR code, and the device will recognise and decode it.
  3. Web-based QR scanners: These QR scanners operate through a web browser. You can visit a specific website or web application, grant camera access, and then scan QR codes using your device's camera.
  4. Handheld scanners: These are standalone devices designed specifically for scanning QR codes. They often have specialised features such as enhanced scanning capabilities, rugged designs for industrial use, and wireless connectivity options.
  5. Embedded scanners: Some devices, such as certain POS (Point of Sale) systems, printers, and kiosks, come with built-in QR code scanning capabilities. These embedded scanners are integrated into the device's hardware and software for specific use cases.
