Making effective QR codes takes work. To shortcut the amount of learning and work required, you can look at how others are using QR codes. By using the best techniques you find and avoiding the worst problems, you can make your QR codes be the best they can be.
Today we look at a QR code that on a product that helps us keep order, a Crowd Control Proline. Similar products can be found at restaurants, stores, churches, and other locations where people need a visual barrier to keep the lines flowing. The interesting thing about this product is the automatic retracting ribbon that you can attach to another Proline post.
This QR code is about 1 inch square. It does not include a call-to-action but nearby, there is a URL.
