How QR Codes Work & Why Use Them

What is a QR Code?

A QR (Quick Response) code is a two-dimensional barcode that can store various types of information, such as URLs, text, contact details, or Wi-Fi credentials. Unlike traditional barcodes that are read by a laser beam, QR codes are scanned using smartphone cameras.

How Do QR Codes Work?

QR codes work by encoding data into black and white (or colored) squares called modules. When you scan the code, your device's software translates these patterns back into readable data instantly. The three large squares in the corners (position markers) help the scanner detect the orientation of the code.

Benefits of Customized QR Codes

  • Brand Recognition: Adding your logo and brand colors makes your QR code instantly recognizable.
  • Higher Scan Rates: visually appealing QR codes attract more attention than standard black-and-white ones.
  • Versatility: Use them on business cards, flyers, product packaging, and digital screens.
  • Error Correction: Advanced QR codes (like ours) include error correction, ensuring they scan even if slightly damaged or covered.

Best Practices for Printing

When printing your QR code, ensure there is high contrast between the code and the background. Always test your code with multiple devices before mass printing. For large formats (billboards, posters), use SVG or high-resolution PNG downloads to prevent pixelation.
