Should I put a QR code on cards I plan to distribute publicly?

Yes, a QR code is one of the smartest additions to a public-facing card. It turns a passive piece of paper into an active link to whatever you want people to do next, and it lets you measure the response.

• Point it at a high-intent destination: booking page, portfolio, menu, or a signup form.
• Use a unique code per location or campaign so you can see which spots actually drive traffic.
• Keep a clear quiet zone around the code and strong contrast so scanners lock on fast.
• Print a test copy and scan it with a couple of phones before you order the full run.
