Dynamic QR Codes in Uniqode offer flexibility by allowing you to update the destination URL without reprinting the code. However, users may encounter issues such as delays in updates, caching problems, or questions about appended URL parameters. This guide provides solutions to these common concerns.
Overview of Dynamic QR Codes
Dynamic QR Codes allow you to change the destination URL even after the code has been printed. This feature is particularly useful for updating links without needing to generate a new QR Code. However, once a short URL is saved, it becomes locked and cannot be edited. To modify it, you must delete the saved card and create a new one, setting the desired short URL before saving.
Common Issues and Resolutions
1. Delays in URL Updates
Dynamic QR Code updates may experience a short delay before taking effect. This is often due to factors like network connectivity, firewalls, or ad-blockers. Typically, these delays last only a few minutes.
2. Caching Problems
If a QR Code still resolves to an old URL after an update, the issue is likely due to browser or device caching. To resolve this:
Clear your browser’s cache and cookies.
Restart your device and try scanning again.
Test the QR code on a different device to confirm the update.
3. Appended URL Parameters
When scanning a QR Code, you may notice extra characters appended to the URL, such as ?uq=. These are tracking parameters added by Uniqode to enhance link security and provide analytics. They do not affect the performance or functionality of the QR Code.
Step-by-Step Guide to Update a QR Code
To update the destination URL of an existing QR Code:
Open the QR Codes page in Uniqode.
Locate the QR Code you want to update and click Edit.
In the destination selector, choose the new Linkpage from the dropdown menu.
Save your changes.
FAQs
Can dynamic QR Codes change the website they point to?
