QR codes are codes which may be scanned easily by devices such as smartphones and cameras. They provide a pictorial representation of URLs (web links) which are more appropriate for this kind of device and easier for them to handle.
There are several ways in which this technology may be used in conjunction with BC CDE:
Labelling physical objects
It may be useful to attach labels bearing QR codes to physical objects. Scanning these labels would then direct the user to the corresponding information in BC CDE. This need not necessarily be a single document but might be a folder or collection containing information relevant to the physical object.
Uniquely identifying documents and objects on the move
Passing URLs to documents uniquely defines those documents but is most appropriate when the users who need to share the information are users of traditional devices such as PCs. However, for smartphone users, traditional URLs can be unwieldy and so identifying documents uniquely by their QR code is more convenient.
Access the latest versions of documents and drawings
It is always vitally important that anyone dealing with documents, particularly drawings, is aware of whether the drawing they are viewing is the latest version or not. When viewing a drawing via BC, a number of mechanisms are in place to ensure that this is made clear to users. However, as soon as a drawing is printed, it becomes much harder to tell if the printed copy corresponds to the latest version. A QR code uniquely identifying the version of the drawing may be obtained from BC and embedded into the drawing. When the drawing is printed, scanning this code will immediately inform the person whether or not the drawing they have is up-to-date.
