Make QR codes that still work after they leave the screen
These guides focus on the decisions that happen after generation: choosing the right code type, preparing artwork, testing real scans, protecting visitor data, and knowing when a dynamic code earns its cost.
Static vs. dynamic QR codes
Choose based on what may change, what needs measurement, and how long the printed item must remain useful.
Quality controlQR code testing checklist
Run a repeatable preflight across phones, lighting, distance, print size, and destination behavior.
Technical guideError correction without the jargon
Understand L, M, Q, and H levels and why choosing the highest setting is not always the safest choice.
Print productionPrinting on paper, plastic, glass, and fabric
Account for glare, texture, curves, folds, ink spread, and the surface surrounding the code.
Trust and safetyQR code privacy and security
Decide what information belongs inside a code and make destinations easier for scanners to trust.
Interactive toolQR code size guide
Start with practical dimensions for cards, menus, flyers, table signs, and posters.
