The SAP Future Retail Center researches usage scenarios with RFID tags. I had the chance to visit it thanks to the Alumni Wirtschaftsinformatik of the University of Zurich.
The technology is already used in closed systems, e.g. during the supply chain on palettes. But there are still some technical issues that prevent RFID tags from being used on every product in retail stores:
A lot of the demonstrations did not work at all.
When scanning a shopping cart, the scanner only recognized 98% of all products.
RFID tags are still too expensive.
There are scanning-problems when the shopping cart contains certain materials. For example:
water (orange juice etc.)
metal (also Tetra Paks)
The market for RFID tags is still fragmented. Most vendors only sell scanners, or tags, but just a few vendors sell everything.
Having in mind that RFID retail stores are a hot topic for years, it was astonishing to see that the prototypes are more a proof-of-concept than really ready for the market.

Afterwards MintBudgeteer calculates your new budget and shows you how much money you have left to buy stuff:
This scenario and the images are taken from a presentation by John Pettengill. He states that future mobile internet should not just be the internet on a smaller screen. The presentation is embedded below. The scenario starts at slide 60.
Youtube implemented the "deep link"-Feature which appeared in newsofthefuture in 2007. The predicted date was quite accurate (October 20th, it was introduced on October 30th) but the year was one year too early. It was introduced in 2008.
