Durability

QR code durability is the ability to remain scannable despite UV, moisture, abrasion, temperature, and chemical exposure. Three factors determine durability: material (paper vs. polyester vs. laser-engraved metal/ceramic), printing method (inkjet vs. thermal transfer vs. UV-cured ink), and error correction level (Level H recommended for harsh environments).

Guidelines: indoor display (1-3 years) uses paper + lamination; outdoor (3-5 years) uses UV lamination + weather-resistant ink; industrial (10+ years) uses laser engraving or ceramic printing.
