Description
QR Code Management issues a QR code for the public pages of posts, fixed pages, and custom post types. QR codes can be downloaded in PNG, SVG, EPS, or JPEG format, embedded in content with a shortcode, and tracked with an access log.
Features
- QR code display — Shows a QR code with a download button on the edit screen and in the post / page list of the post types you choose.
- Output formats — Download QR codes as PNG, SVG, EPS, or JPEG.
- Redirect (shortened URL) — Embeds a shortened URL (
https://your-site/?qrc=CODE) instead of the page URL. Each scan is recorded in an access log and redirected to the current permalink, so printed QR codes keep working even when the page URL changes. - Access report — See the number of scans, unique visitors, and the last scan date for each QR code over the last 7 / 30 / 90 days or all time, and download the report as CSV. The scan count is also shown in the post list.
- QR code data — Embeds the permalink by default. Per post, it can be changed to a URL, contact information (MeCard / vCard), event information, or free text.
- Appearance settings — Margin, error correction level, label, size, colors, logo image, and background image can be set globally or per post.
- Original QR codes — Create QR codes that are not tied to a post, with any data.
- User profile QR codes — Issue QR codes for users. They redirect to a URL configured in the profile, or to the user’s author archive page.
- Role settings — Choose which post types and user roles can use the QR code features.
- Shortcodes —
[qrcm]embeds a QR code in content (attributes:post_id/user_id; without attributes it shows the QR code of the current post or author).[qrcm_scanner]places a camera-based QR code reader that redirects to the scanned URL. - Sidebar widget — The «QR Code (QR Code Management)» widget shows the QR code of the page being viewed.
Usage
- After activation, open «QR code management» -> «Setting» in the admin sidebar.
- Choose the target post types, user roles, data formats, and output formats.
- QR code meta boxes (data, settings, shortcode) appear on the edit screens of the selected post types, and a QR code column appears in the list screens.
See the plugin site for detailed documentation (Japanese / English).

FAQ
-
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.
-
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. -
Where can I see how often a QR code was scanned?
-
In «QR code management» -> «Access report». Scans are recorded only while the redirect setting is enabled, because the scan is counted when the shortened URL is opened.
-
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.
-
Does the data remain after uninstalling?
-
Yes. The options, post / user metadata, and the access log are not deleted when the plugin is removed.
