Help
Most problems with a printed code are print problems. Start with the six causes, in the order they actually happen.
Where do I get help with a QR code that is not working?
Start with the troubleshooting article below: it lists the six causes of a code that stopped working, in the order they actually happen, with the check for each one first. Most failures are print or camera problems rather than anything wrong with the code itself.
Common questions
The ones people arrive with, mostly about whether a printed code keeps working.
Will my QR code stop working?
Not one of ours, and this is the question worth settling before anything goes to print. A Klip link has no expiry date on any plan, including free, and there is no interstitial or ad in front of it. The pattern on the paper is permanent; what can change is where it points, and only when you change it.
Do QR codes expire?
The symbol itself never expires. It is a printed pattern, not a subscription. What expires is whatever the code points at: a static code dies when its web address dies, and a dynamic code dies if the company running the redirect stops answering. That second case is the one to ask providers about, because it is the one that turns a print run into waste.
What happens to my codes if I stop paying?
They keep resolving. Downgrade, cancel, or disappear entirely and every printed code still works. What you lose is scan history, custom domains, and the ability to create new links. A code on somebody's wall is their property as much as yours, and switching it off to collect a subscription is not a lever we are willing to hold.
Will my code stop working after a free trial?
There is no trial to lapse. The free tier is a plan, not a countdown, and its links never expire. Some providers do expire free links after a trial period, which is worth checking on any code you have already printed elsewhere.
How much can a QR code hold, and does it change the size?
Yes, and this is the practical reason to encode a short link rather than a long URL. More characters means more modules in the same square, so each module is smaller and the code has to be printed larger to stay readable at the same distance. The size calculator shows the difference for your scanning distance.
Can I see how many times a code was scanned?
Yes, on every plan including free. Scans are unlimited and never metered. What you get is the count, the hour, the coarse region, and whether the scanner was on Android or iOS, with link-preview bots from Slack, WhatsApp and iMessage counted separately so the number means people rather than traffic.
Can I change where a code points after it is printed?
That is the whole point of a dynamic code. Change the destination and the next scan follows worldwide inside a minute, with no reprint and no new code. A static code cannot do this: the address is inside the pattern, so the only remedy is reprinting everything.
