QR codes are powerful, but they are fragile if not designed correctly. Here are mistakes to watch out for.

1. Low Contrast

Using light colors on a light background renders the code unreadable to most cameras.

2. Broken Links

Always test your QR code before printing! There is nothing worse than a permanent print run leading to a 404 page.

3. Too Much Data

The more data you pack into a QR code, the denser and smaller the dots become. Use a URL shortener to keep the code clean and simple.
