The BBC has a video report about a German supermarket Future Store from German supermarket chain, Real.
Rather than use RFID tags to do the scanning of all the stuff in your shopping trolley (that’s ‘cart’ to you folks over the Atlantic), they’ve gone for a mobile phone solution. Basically you take photos of all the bar codes and their phone software generates one master bar code that you scan back in (very meta-media that) at the end in order to pay.
They do use RFID tags for their ‘smart freezers’, which know what meat has been taken out and sold. But the best feature, which requires very little in the way of tech, is the self-service wine-tasting. That’s a really smart idea.
My supermarket here in Germany doesn’t take credit cards, only EC Cards and Germany is a very paper and cash oriented culture I’ve found. I wonder how this will pan out… Personally I’ve really been enjoying the whole Richard Scarry small town experience with a baker and a butcher, etc., all of whom know me.
