Frequently asked questions about QR Code Management.
The QR code meta boxes do not appear on the edit screen
Check that the post type is enabled in the role settings under “QR code management” → “Setting”. Your user role also needs to be included in “Available permissions”.
What data goes into the QR code?
By default, the URL of the public page (a shortened URL when the redirect is enabled). For each post, the “QR Code Data” meta box lets you change it to a URL, contact information (MeCard / vCard), an event, or free text (only the data formats allowed in the settings).
Do I need to reissue QR codes when a page URL changes?
Not if the redirect setting is enabled: the QR code contains a shortened URL that redirects to the current permalink at scan time. If the redirect is disabled, the actual URL is embedded directly, so you need to reissue the QR code after changing the URL.
Can I embed a QR code in post content?
Yes, with the [qrcm] shortcode. The “QR Code Shortcode” meta box on the edit screen shows the shortcode for that post. See the documentation for details.
Where does a user QR code redirect to?
To the URL configured in the profile. If it is not set, it redirects to the user’s author archive page. Note that a bug where user QR code redirects did not work was fixed in 1.5.2.
Which formats can I download?
PNG / SVG / EPS / JPEG. You can choose the allowed formats in the output setting.
Can I see how many times a QR code was scanned?
When the redirect is enabled, each scan is recorded in the access log (the rwc_qrcm_log table) in the database. A report screen for viewing the statistics in the admin panel is under preparation.
Does the data remain after uninstalling?
Yes. The options, post / user metadata, and the access log are not deleted. If you do not need them, delete them manually — see the list in the documentation.
