RE:WalmartPeople have to figure out where and when to place these devices. Is it worth their expense and how much area of their business they can cover. If the devices are not installed in the parking lots well it goes without saying. I am not ruling things in and out as that isn't my place to predict who will have these devices and who will not but the one thing that we know is that there is a very strong demand for them and a large market potential to earn a good chunk of money for what the company has to offer. The rest as i said in my last response will need to be seen as to who will bring the tech in.
good luck all.
