Sales through retail chains can often be a pain, especially when it comes to reporting, a lot of businesses rely on restock numbers to calculate sales. Which are of course quite delayed (in terms of reporting) and not often accurate.
So what can you do to get live sales reporting?
Using RFID technology and a detector at the store front (which can be a small unit) you could tell when your stock left the store, hook that up to a 3G device and you can get live sales reporting.
Which would make things much more interesting. Simple technology, someone please do it, or if it exists implement.
