The different levels of error-correction available

When it comes to QR codes, error-correction plays a crucial role in ensuring the readability and reliability of the codes. Error-correction is the ability of a QR code to withstand damage or distortion and still be accurately scanned and decoded. In other words, it acts as a safety net to prevent the loss of vital information encoded within the QR code.

QR codes offer four different levels of error-correction: L, M, Q, and H. Each level provides a varying degree of resilience against damage and allows for different amounts of data to be stored within the code.

The L (Low) level of error-correction is suitable for QR codes that will be placed in controlled environments, such as on websites or digital advertisements. This level of error-correction can only withstand up to 7% damage or distortion.

The M (Medium) level of error-correction is commonly used for QR codes printed on business cards, flyers, or brochures. It can handle up to 15% damage or distortion, making it more resilient than the L level.

The Q (Quartile) level of error-correction is ideal for QR codes placed in outdoor settings or areas prone to wear and tear. It can tolerate up to 25% damage or distortion, making it a reliable choice for applications where the code may be exposed to environmental elements.

Lastly, the H (High) level of error-correction provides the greatest level of resilience, able to withstand up to 30% damage or distortion. This level is commonly used for QR codes engraved or etched onto durable materials like metal or stone, ensuring longevity and readability even in challenging conditions.

When creating QR codes for memorial plaques, it is crucial to choose the appropriate level of error-correction based on the specific use case and the environment in which it will be displayed.
