QR code accessibility

The use of Quick Response (QR) codes as an alternative to Braille or printed text for encoding information in tactile graphics, product labels, or physical environments that can be read by smartphone cameras. QR codes can encode 45% more text than Braille in the same physical space, can be generated for free, and are accessible to the estimated 60% of blind people who are not Braille-fluent. When paired with smartphone applications that provide audio feedback, QR codes bridge the gap between tactile physical materials and digital information, enabling independent access to labelled content without specialized hardware.
