A QR code (Quick Response code) is a two-dimensional barcode that can be scanned using a smartphone or QR code reader to quickly access information, such as a website or contact details. It consists of black squares arranged on a white background, encoding data in a compact and efficient manner.

The usage of QR codes includes these and much more.

  1. Marketing: Linking to websites, promotions, or product information to engage customers.
  2. Event management: Streamlining ticketing and registration processes.
  3. Asset tracking: Managing inventory or equipment in various industries.

Remember to use QR codes in a way that is convenient, efficient, and adds value for users.

QR code error correction uses Reed-Solomon algorithms to add redundancy, enabling data recovery if the code is partially damaged. There are four levels: L (7% recovery), M (15% recovery), Q (25% recovery), and H (30% recovery). Choose a level based on the application, risk of damage, and data importance, balancing error correction with code size.
