The QR codes in all Pawnec tags are still readable after being reasonably exposed to dirt, stains, or scratches.
Every QR code on it has an 30% error tolerance. This means 30% of the QR code (excluding the corner elements) can be removed, and the QR code will still work. This is on top of the embedded backup NFC to still make your Pawnec tag accessible when all else fails.
The commonly used QR codes we see every day, especially from free QR code generators, are not as durable as it only has a 7% to 15% error tolerance. That easily makes Pawnec’s advanced QR codes twice as durable as other QR codes.
