iOS Developer for Verizon's in-store experience application, 'Smart'. Smart is included in the My Verizon Mobile
application. When the user enters a Verizon Wireless retail store they will receive a welcome notification,
allowing them to automatically check into line, view promotions specific to their current store location,
automatically detect and display product information about products they are standing by (as the user walks
