Practical articles to help you get the most out of dynamic QR codes — from restaurants to events, marketing to networking.

A printed QR code is a decision you have already paid for. Changing where it points should not need a dashboard — and with MCP it does not.

How to Scan a QR Code on iPhone and Android

Almost every phone made in the last several years scans QR codes with the built-in camera and no app at all. Here is where it is, and what to do when nothing happens.

How Do QR Codes Work?

A QR code is a short piece of text, written in a grid, with enough redundancy to survive being printed badly. Understanding the three parts explains almost every practical rule about using them.

Why Is My QR Code Not Working?

A code that will not scan is almost never a broken code. It is usually too small, too crowded, too low-contrast, or pointing somewhere that has moved.

Are QR Codes Safe?

The code itself cannot hurt you — it is inert text. The risk is that a QR code is unreadable to humans, which makes it an unusually good way to hide a link.

What Is a Dynamic QR Code?

A dynamic QR code stores a redirect, not a destination. That single difference is what lets you change where a printed code leads, measure who scanned it, and switch it off when a campaign ends.

Do QR Codes Expire?

The pattern itself never expires — it is just squares. What expires is whatever the code points at, or the account holding the redirect. Here is what actually breaks, and how to stop it.

The Best QR Code Size for Printing

The rule is simpler than it looks: the code needs to be about a tenth of the distance it will be scanned from. Everything else is quiet zone, contrast, and testing a real printed proof.

Static vs Dynamic QR Codes: Which Should You Use?
