Mobile barcode usage in museums is just now starting to take shape. I’ve put together a sampling of some uses ranging from audio tours to augmented reality. There have been some miscues along the way, like laminating the QR code or putting it behind glass so that when the light hits it at the right angle, it’s impossible to scan correctly. Oops! But there have also been many successful implementations. QR codes are a great way to enhance the visitor’s experience. They can bring life to exhibits, allow communication between visitors and educate at all levels.
