QR Redirector is an update to my old QR Code Redirect plugin. Unlike the old plugin, which relied on Google Charts API, this version is completely self-contained.
A little experiment I created, since my employer has an interest in QR Codes. My new QR Redirect Plugin lets you redirect a WordPress permalink anywhere you want, and never have to update the QR code that points at it.
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.
