Description
QR Code error correction (ECC) levels ensure QR codes remain scannable even if damaged or dirty. These levels use the Reed-Solomon algorithm to add redundancy, allowing data recovery. However, [Platform/Tool Name] does not currently allow users to choose an ECC level when generating QR codes.
This feature request proposes adding an option to select ECC levels for better customization and reliability.
Problem Statement
Users cannot currently specify ECC levels, which impacts QR code reliability in different environments. Higher ECC levels improve data recovery but increase the QR code's complexity. Without control over this setting, users may face issues with scannability, especially in challenging conditions.
Proposed Solution
  • Introduce an ECC level selection option (
    L
    ,
    M
    ,
    Q
    ,
    H
    ) in the QR code generation process.
  • Provide a brief explanation of each ECC level’s impact on error correction and QR code size.
  • Implement validation to ensure compatibility between ECC level, data size, and QR code version.
  • Set a default ECC level (e.g.,
    M
    ) for users who do not specify a preference.
ECC Levels Overview
  • L (Low):
    Recovers up to
    7%
    of data. Best for clean environments with minimal damage risk, such as personal use and basic marketing.
  • M (Medium):
    Recovers up to
    15%
    of data. Suitable for general-purpose marketing campaigns where minor damage is possible.
  • Q (Quartile):
    Recovers up to
    25%
    of data. Used in high-risk environments such as logistics and healthcare.
  • H (High):
    Recovers up to
    30%
    of data. Ideal for extreme conditions (manufacturing, construction) or embedding logos in QR codes.
Impact & Benefits
  • Enhances QR code reliability by allowing users to choose the right level for their needs.
  • Helps users balance
    scannability
    ,
    redundancy
    , and
    QR code size
    .
  • Provides better
    customization and control
    over QR code performance.
