Location based services

Are location based services the next billion dollar idea?

In the US, in-shop services are common by now but in europe is a huge potential in that field left. With Apples iBeacon, indoor navigation based on bluetooth low energy technology is possible. 

The are 3 challenges when working with that new technology:

1. data privay
2. user acceptance 
3. usability

Don't try to build an in-shop service without a real benefit. A good usage are an indoor navigation and couponing. Give your customer the feeling that their datas are save and anonym (even though if you use them for personal ads). Have in mind your customers are using their smart devices so they expect a rocking user interface.
