Every QR code we generate conforms to the ISO/IEC 18004 standard that every compliant scanner has supported since 2006. Any phone camera or QR reader that claims QR support will read our codes.
Native camera-app support is now the norm rather than the exception. iOS 11 and later (released 2017) recognizes QR codes directly in the Camera app with no third-party scanner. Android 8 and later supports codes through Google Lens, which is preinstalled on every Google Play device. Combined, those cover roughly 99% of phones in normal consumer use in 2026.
The small fraction of devices that don't have native support — older budget Android phones, some Chinese market ROMs without Google Play, older feature phones — can still use a free QR scanner app. The code itself is identical; only the phone's built-in handling differs.
For the rare production scenario where a QR absolutely must scan on everything (medical packaging, industrial safety signage), the practical answer is to make the code larger and use error-correction level H so noisy or partially occluded reads still succeed. We cover the exact ratios in the logo-overlay guide.
