Guide
Beyond the basics of generating a code, there's a layer of technical decisions that matter more as usage scales up — how dynamic codes actually work under the hood, what kind of data you can realistically get back from scan analytics, and what security risks QR codes introduce that are worth understanding before deploying them at any scale. This guide covers the topics that come up once you're past "how do I make a QR code" and into "how do I use these responsibly and effectively."
A dynamic QR code encodes a redirect rather than a final destination, which is what allows the destination to change after the code is printed. This covers how that redirect works, what it costs you in tradeoffs, and how to decide whether a given use case actually needs it.
Dynamic codes make scan tracking possible, but what you can actually learn from that data — and what you can't — is often misunderstood. This covers what metrics are realistically available and how to use them well.
Because a QR code hides its destination until scanned, it's become a vector for phishing and scam attempts — "quishing." This covers the specific risks and how to verify a code is safe before scanning it, or reassure others that one you've published is trustworthy.
