QR codes are two-dimensional bar codes that contain varying amounts of information. Simple versions contain basic details such as a part number, but some more complicated versions can contain complete web page data.
These codes were originally used by Toyota to track various items in their vehicle assembly plants, Now they commonly contain a web site URL for users to scan with their smartphone or tablet computer and then can see the complete parent web page. The latter is the use we are exploring.
Once we decide how to get these codes printed, we will fix them to interpretative signs on our History Trail to enable visitors to access more detailed information about Williams House and the grounds.
