Frequently Asked Questions

Usually, if the logo is small. QR codes use Reed-Solomon error correction, and Level H recovers roughly 30% of codewords, but that budget is also spent on print defects and glare. Keep a centered logo to about a tenth of the symbol area, keep every finder and timing pattern clear, and test each printed proof rather than relying on a fixed percentage.

No. A static code stores its data in the pattern itself, with no expiration date and no dependence on a redirect provider. It keeps working as long as the print stays legible and the destination page stays online, so the real risk is the page or domain, not the code.

Print a human-readable alternative beside every code, such as a short URL or phone number, and make sure the destination page meets WCAG 2.2 for contrast, touch targets and screen readers. Not everyone can scan, so the printed text keeps the information reachable.

There is no official minimum. A common rule of thumb is about 2 cm (0.8 in) for handheld items such as business cards and receipts. For greater distances, divide the scanning distance by 10 to get a starting width. Test a printed proof on the real surface either way.

Add UTM parameters to the URL before you generate the code, with a different utm_source for each placement and utm_medium set to qr_code. Google Analytics 4 then reports visits by source. It counts page visits rather than scans, so treat the numbers as a floor.

Only where you expect the destination to change after printing, such as a seasonal menu or rotating offer. For stable destinations a static code costs nothing and has no provider to lapse. A static code pointing at a redirect path on your own domain is a middle option.

Usually one. A single code with a clear instruction and one destination is easier to scan and to measure than several competing ones. If you need more than one action, send the code to a landing page that offers the choices.

Print the destination domain beside the code, place codes where staff pass them, and check for overlays at opening time. The FBI has warned that criminals tamper with physical QR codes, so a visible domain lets customers compare it with what their phone shows.
