Problem (this section should probably be removed or integrated into the previous section)

Currently BLE indoor positioning techniques can accurately target low energy devices within the .4-1.5 meter range.  While this is close enough for implementing positioning for uses mentioned before, improving this accuracy could make advancements for other uses of BLE.  One particularly valuable implementation of BLE indoor positioning would be product payment and checkout.
If indoor positioning could be developed to the point of accurately locating products to within several inches, it could be feasibly implemented to automatically charge a user’s cell phone (through apps such as Cash or Venmo) as they walked out of the store with a product.  This implementation of BLE indoor positioning would be a game changing development to all aspects of shopping and retail.
