QR Code Redirect lets you set up your own QR Code redirection site. Generate a QR code for a URL on your site, and redirect that URL anywhere.
QR Code Redirect lets you set up your own QR Code redirection site. The plugin creates a new custom post type called QR Redirect, which generates a QR code that points to the post's permalink. You may then specify any URL you like for the post to redirect to. Great if you have an offsite contest, form, newsletter sign-up, etc. You can even change the URL you're redirecting to without having to worry about updating the QR code in your advertising media.
