    Also known as:
    
    block interleaving
    
  

  

  
  
The process of distributing data and error correction codewords across multiple blocks before placing them in the QR code. Interleaving ensures that localised damage (e.g., a scratch across one area) affects codewords from different blocks, enabling each block's Reed-Solomon decoder to correct its share.
