Hi, Inside of buildings navigation will soon be provided by radio frequency. For example, when you walk in to your local walmart, your greeter will offer you a gadget that uses radio frequencies to triangulate your position in the building in relation to department markers and isle signs. The device will alert you to these as you pass the end of the isle or move from department to department.
Each item in the store inventory will be tagged with a radio frequency chip which when swiped on your walmart gadget will give you all the product info on that item. Because the chips are radio frequency, your check out will be set up so that when you roll your cart through, it will automatically swipe all items in the cart in a time that seems instantaneous to us. You'll be able to do all your own shopping using the same equipment sighted people are going to use, and walmart will make billions.
