- Error correction
- Extra data built into every QR code that lets it be read even when part of it is covered or damaged, roughly 7 to 30 percent depending on the level. It is what makes a logo in the middle possible.
- Finder patterns (eyes)
- The three large squares in the corners of a QR code. They let a camera find the code and work out which way up it is. Design editors often call them eyes and let you change their shape and color.
- KuikPage
- A mobile page built in KuikCode from templates and blocks, published on a kuik.page address and usually opened by a KuikCode. A KuikPage can have several pages with a menu. KuikPages
- Mobile landing page
- A short, phone sized web page built for one purpose, such as a menu, an event or a product. It is often what a QR code opens instead of a full website. What is a mobile landing page
- Module
- One of the small dark or light squares that make up a QR code. Design editors can draw modules as dots, rounded squares or other shapes, as long as the code still scans.
- Quiet zone
- The empty margin around a QR code. It separates the code from its surroundings so the camera can find its edges. Frames and designs should keep it clear.
- Retargeting pixel
- A small script from an ad platform, such as the Meta Pixel or a Google Ads tag, that lets you show ads later to people who scanned. It should only run with the visitor's consent where the law requires it.
- Scannability
- How reliably a QR code can be read by phone cameras. Contrast, size, the quiet zone and how heavily the code is styled all affect it. KuikCode checks every design before you download it.
- Short link
- The short web address a dynamic QR code stores, such as kuikco.de/p/ followed by an ID. It never changes, while the destination it forwards to can.
- Smart rules
- Conditions that send one QR code to different destinations, for example by device, country, language or time of day. Also called redirect rules or smart routing.
- SVG
- A vector image format. An SVG QR code stays sharp at any size, which makes it the best choice for print. PNG and JPG are raster formats suited to screens and documents.
- Unique scans
- An estimate of how many different people scanned a code, as opposed to total scans. It is usually worked out from anonymous signals without storing personal data.
- UTM parameters
- Tags added to a web address, such as utm_source and utm_campaign, that tell analytics tools like Google Analytics where a visit came from. A QR code can add them automatically.
