About QR Code (High)

Example: WiFi: MyNetwork

Character Set: UTF-8 text, URLs, numbers

QR Code (Quick Response) with High error correction level provides approximately 30% error recovery capability, representing the maximum reliability available in QR code technology. This format prioritizes absolute readability over data capacity, making it essential for mission-critical applications where code failure is not acceptable under any circumstances.

Maximum Protection:

~30% error correction capability
Highest damage tolerance available
Minimal data capacity (maximum reliability)
Extreme environment performance

Critical Applications:

Industrial tracking and manufacturing
Extreme outdoor conditions
Mission-critical identification
Long-term archival applications

Ultimate Reliability: High error correction enables QR codes to remain readable even with substantial damage, dirt, or printing defects. This level is crucial for applications where code failure could result in significant operational disruption, safety concerns, or financial loss, providing the highest possible assurance of successful scanning.

Mission-Critical Use: Essential for aerospace, defense, medical devices, and industrial applications where absolute reliability is paramount. The format's extreme fault tolerance makes it valuable for permanent installations, safety-critical identification, and any scenario where re-printing or replacement would be extremely difficult or impossible.
