QR codes
Digital ticket patterns
QR codes are two-dimensional barcodes—square patterns of black and white modules that encode information readable by smartphone cameras and scanners.
Originally developed for tracking auto parts, they now appear everywhere: restaurant menus, payment systems, event tickets, product packaging.
Scanning a QR code typically opens a website or displays text.
Scan the QR code to see the menu.
