This document provides design considerations for creating QR codes, including using 30% error correction, using .eps and .png file extensions for printing and .png and .jpg for the web, using a minimum resolution of 300 dpi for printing, choosing contrasting colors and avoiding interrupting the safe zone around the original QR code, using black as the safest color, educating clients on the best mobile readers to scan codes, and providing instructions on scanning codes.
