How QR Codes Work and How to Test Them
Learn what a QR code stores, when to use a URL QR code, and how to test a QR code before printing or sharing it.
What a QR code stores
A QR code stores text data, most commonly a URL. When someone scans it, their phone reads the encoded text and opens or displays it.
Static QR codes contain the exact text you entered. If you need to change the destination later, use a redirect URL that you control.
Testing before sharing
Always scan the final QR code with a phone before printing it on a flyer, package, menu, or sign.
Check that the destination opens correctly, the printed size is large enough, and there is enough contrast around the code.
Frequently asked questions
Can a QR code contain plain text?
Yes. A QR code can store a URL, short note, contact text, or other plain text.
Can I edit a static QR code?
No. A static QR code stores fixed text. Generate a new code or use a redirect URL if you need to change the destination later.
