Fraunhofer Institutes's intelligent scales. Not a new idea, we saw IBM's Veggie Vision at a Metro Extra Store as far back as 2001. The idea is to have a camera on a scale that can recognize at least the category of a piece of produce and ring up the proper cost based on weight. Some human interaction needed for recognizing similar types.
The Fraunhofer example seems to have closer links to a vendor, Mettler-Toledo. They are being tested in 300 stores throughout Europe. More here.
