Knowledge base
What is a QR Code and how does it work?
A QR code is a matrix barcode that stores encoded data (most commonly a URL) in a square pattern that smartphone cameras can decode. It acts as a bridge between physical and digital experiences by letting users jump from posters, packaging, menus, and product tags directly into websites, checkout flows, videos, or messaging channels.
For marketers, this means offline media becomes measurable: each scan can route to campaign-specific landing pages, lead forms, or offers. Combined with UTM-tagged links, QR campaigns provide attribution data that helps teams optimize channel spend and creative placement.
Best Practices for QR Code Marketing
- Use high-contrast colors (dark code on light background) and avoid low-contrast brand combinations that reduce scan reliability.
- Size for context: small labels need larger quiet zones, while long-distance signage requires much larger code dimensions.
- Always use UTM-tagged destination links to track scan performance by placement, campaign, and audience segment.
- Test across iOS and Android devices under realistic lighting before sending to print.
Frequently asked questions
Do QR codes expire?
Static QR codes do not expire because they directly encode the destination text or URL. A QR campaign can effectively “expire” only if the destination page is removed or redirected incorrectly.
How much data can a QR code hold?
Capacity depends on encoding mode and error-correction level. In marketing practice, shorter URLs scan faster and more reliably than long payloads, especially on low-light mobile cameras.
Should I always use UTM-tagged links in QR campaigns?
Yes. UTM-tagged links help measure source, medium, and campaign performance in analytics platforms, so you can attribute scans to specific print placements, stores, or promotions.
What print size is recommended for QR codes?
As a rule of thumb, use at least 2 x 2 cm (about 0.8 x 0.8 in) for short scanning distances and increase size for posters, packaging, or billboards viewed from farther away.
