Just thought I'd comment on the shopping experiences. Shopping experiences are changing. Consumers are taking the internet shopping to new levels. The internet is full of reports stating that online is taking a bigger share of revenues. Just as a silly example amazon.com has been doing nicely according to the stock markets ? See the 6 year chart after the tech-bubble.
The x, y and upcoming z generations are all accustomed to the online shopping experiences. This trend will spread. In the future i.e. 5 to 10 years more stuff will be bought online. Why bother traveling to a shop when you can get it delivered home?
Shopping is done via the internet (PC) and increasingly via mobile phones either by adding the shopping/content to ones phone/carrier bill or paying with a credit card. Anyways...
In the meantime:
A chain of German supermarkets have utilized cell phones to make it possible for the purchases to be scanned directly from the cell phone. As you go through the store you use the camera on your phone to scan each item. Once you’re finished shopping you press a button on the phone to conclude the process which brings up a barcode on the screen. You allow the machine near the door to scan the barcode and you pay there.
Sounds nice and its happening. Similar stuff can be and has already been considered using Radio-frequency identification (RFID) tags. http://en.wikipedia.org/wiki/RFID
It has also been proposed to use RFID for store checkout to replace the cashier with an automatic system which needs no barcode scanning. Initially this would mean that the shop would have for example “doors” scanning your groceries and cashiering your wallet/credit card or cell phone.
Hmm... We need to start taking those Japanese comics seriously with humans having stuff implanted in their bodies and cars flying around.
