How to Test a QR Code Before You Print 5,000 of Them

Seven checks, in the order that catches the most for the least effort. The one that matters most costs the price of a single sheet of paper: print one proof and scan it where the code will actually live, with a phone that is not new.

How to Edit a QR Code (and When You Cannot)

One QR Code for App Store and Google Play

The app-store code reads the phone's operating system and sends iPhones to the App Store, Android phones to Play, and everyone else to a fallback link. The fallback is the field people leave empty and then wonder why the poster does not work on a laptop.

QR Codes and GDPR: What Gets Collected and What to Say About It

A scan here records a timestamp, device, OS, browser, referrer and a salted hash of the IP address. No location, no identity, no cross-site tracking. Here is what that means for your privacy notice — and where your own obligations start, which is the moment you switch on retargeting pixels.

QR Code Error Correction Levels L, M, Q and H: Which to Use
