Educational information
Understanding QR codes
QR codes are two-dimensional optical symbols designed to represent information in a machine-readable format. Reliable scanning depends on both the encoded data and the physical quality of the final symbol.
Quiet zone
The clear area surrounding a QR code helps scanning systems identify the boundary of the symbol and distinguish it from nearby visual elements.
Contrast
Strong visual contrast between the modules and their background generally improves scanning reliability, particularly in printed material.
