To test the QR code if it works, you have to scan it. This can be done with the camera of your mobile phone or a QR code scanner application.
After scanning, check whether you are directed to the correct page/file.
Check this before and after you have printed and used the QR code.
If the QR code does not work, this may be due to the design, a expired paid plan or the plan is over it's scan limit.
Has your QR code expired and want to activate it again? No problem, just follow these steps:
Inform the owner about the expired QR code
Login as the owner of the QR code on app.trueqrcode.com
In the left menu, click on 'Manage plan' and upgrade to a suitable paid plan
After the upgrade, your QR code will work within 1 minute. Question about this? Contact our support by our chat.
