Error Correction Level

This barcode type uses a Reed-Solomon error detection and correction scheme. There are four levels of error correction, each with increasing amount of error recover. Note: The higher the error level, the less data that can be stored in the barcode.

• "L" - 7% error recovery
• "M" - 15% error recovery
• "Q" - 25% error recovery
• "H" - 30% error recovery
