What's the difference between a static and dynamic QR code?

A static QR code permanently encodes data directly: once printed, you can never change it. A dynamic QR code uses a short redirect URL, so you can update the destination, track scans, and change content anytime without reprinting. We recommend dynamic for any printed materials.

Do I need to download an app to scan QR codes?

No. iPhones running iOS 11 or later and Android phones running Android 8 or later can scan QR codes natively in the camera app. Just point the camera at the code, no app download required.

How small can I print a QR code and still have it scan reliably?

As a rule of thumb, the minimum printable size is 1 cm × 1 cm (about 0.4 inches) for close-range scanning on modern phones. For anything that needs to be scanned from more than 30 cm away, use 2 cm or larger. Always test before going to print.

Can I change the URL a QR code points to after printing?

Yes, if it is a dynamic QR code. Log into your ScanOrbit account, open the QR code, and update the destination URL. The change takes effect immediately. Static QR codes cannot be changed.

Why does my QR code look different on iPhone vs Android?

The QR code itself is identical on all devices: only the visual rendering of the scanner interface differs. If a code scans on one device but not another, it's usually a printing issue (too small, low contrast) rather than a code issue.

How do I add a logo to my QR code without breaking scannability?

ScanOrbit automatically increases error correction to 'H' level when you add a logo, which allows up to 30% of the code to be obscured. Keep your logo below 30% of the total code area, and always test scan after adding it. We also recommend high contrast between your logo background and the QR code.

Can I track which specific print material a scan came from?

Yes: create a separate dynamic QR code for each print material (flyer, poster, packaging, etc.) and group them in a folder. Each code tracks its own scans independently, so you can compare performance by material.

Is there a limit to how many scans a QR code can receive?

Dynamic QR codes on the Free plan are limited to 500 tracked scans per month. Pro and Business plan codes have unlimited scans. You can also set a manual scan limit as an access control feature on any plan.

What happens if I delete a QR code?

Deleting a dynamic QR code will break the redirect: anyone who scans it will get a 404 error. We recommend deactivating rather than deleting if you might want to restore it later. Static QR codes are not affected as the data is embedded permanently.

Can I use ScanOrbit for free forever?

Yes. The free plan includes 3 dynamic QR codes, unlimited static QR codes, 500 scan tracking per month, and 30-day analytics history, with no expiry date. No credit card required.

Password-protecting your QR codes

Put a password in front of a QR code's destination so only people with the passcode can open it. How to turn it on for a dynamic code on the Pro plan.

Password protection places an access gate in front of your destination, requiring scanners to enter a passcode before accessing confidential links or materials.

Enabling password protection

1Open any dynamic QR code (Pro plan required).
2Under Advanced Options, enable Password Protection.
3Enter your chosen passcode.
4Save changes.

User scanning experience

Scanners are presented with a branded passcode verification screen. Upon entering the correct password, they are redirected immediately to the destination.

Passcodes can be updated or removed at any time in your dashboard without altering the physical QR code.

Setting expiry dates and scan limitsMake a QR code stop working on a set date or after a set number of scans, for limited offers and events, and what people see once it has expired.Managing active and inactive QR codesPause, reactivate or delete QR codes in ScanOrbit. Pausing stops redirects but keeps all scan history, while deleting removes the code and its data for good.
