Should shoppers turn off their smartphones when they hit the mall? Or should they leave them on? Retailers are using mobile-based technology to track shoppers movements at some malls and stores.

Some say it's spying and shoppers should be informed their phones are being observed and then be able to choose whether to allow it. What do you think?
