No to the higher education, but I work for Ford Motor Company and we use the QR codes on alot of parts. The code contains the date, time, shift, operator, vendor or in house info. Also on the bottom of every vehicle, there is a QR code that is easily scanned to tell dealers when the vehicle left the build lot, then arrive at the dealerships and how many where in the shipment in case one *just happens to fall off the truck*.
*just happens to fall off the truck* <---- this has happened on more than one occasion, meaning the truck driver has done something with the vehicle.
Some businesses are reluctant to upgrade their systems as it takes cash plus they dont seem the need to spend millions just to get the same results with new equipment that they would get with older stuff. We still have alot of robots running on Windows 2000. They dont take alot of memory or cpu power to operate them as they are only programmed once and the program executes and the plc's do the rest.
