How QR codes work, in five short reads
The questions people type before they look for a generator, answered plainly: what the two kinds of code contain, how big a printed code must be, how to put a logo in one, whether a code can expire, and what the error-correction setting does. Each guide ends where the feature pages begin.
Static vs dynamic QR codes
What a static and a dynamic QR code actually encode, what that means once the code is printed, and a plain rule for choosing between them.
Read the guide →QR code size for print
The minimum QR code size by scanning distance, the quiet zone, why module count matters, and which file format to give your printer.
Read the guide →How to add a logo to a QR code
Why a logo in the middle of a QR code still scans, how big it may be, which error-correction level to set, and the steps to make one in QR Solutions.
Read the guide →Do QR codes expire?
A static QR code never expires. A dynamic code lasts as long as the service behind it says it does. The real reasons a printed code stops working, and how to avoid them.
Read the guide →QR code error correction explained
What the four error-correction levels of a QR code do, how much damage each one survives, what they cost in size, and which to choose for print, screens and logos.
