What Can You Do with a QR Code?

QR codes turn any URL or text into a scannable image that works with every smartphone camera. Print one on a business card linking to your portfolio, stick one on a restaurant table linking to the menu, or put one on a poster linking to a sign-up form. Unlike short links, QR codes work in the physical world — anywhere you can print or display an image.

Tips for Better QR Codes

Shorter content makes simpler codes that scan faster. Use a URL shortener before generating the QR code
Keep high contrast between foreground and background — low contrast codes are hard for phones to read
Print size should be at least 1 x 1 inch (2.5 cm). Smaller than that and scanners struggle
Always test scan your QR code before printing to make sure it opens the right link
